Home Experiment for HS Students: Importance of Brushing our Teeth

Wednesday, June 23, 2021

It all started when my eldest daughter sought my help for her school project. They need to present an experiment which they could perform at home. Believe me, it wasn't easy to come up with on for the obvious reason that we lack materials and equipment at home. 

Initially, we thought to do an experiment about whether plants would grow better with more human attention than not, but this is not the growing season so it didn't work.

Then I remembered this commercial about a toothpaste when I was young. In the commercial, they brushed a couple of shells with brand x and y toothpaste and then immersed them both for 24 hours in bleach.

We had to replace the shells with eggshells to accelerate the results and replaced the objective by pointing out to the importance of brushing our teeth in general than comparing brands as this was not a marketing experiment.

Finally without further ado, let's jump in. And by the way, credits are all to my fantastic daughter who is too modest to take the lime light.

Purpose of the experiment

The objective of this home experiment is to show the importance of brushing one's teeth and possibly, to also discourage us from eating too much acidic foods. 

At first, we didn't think that there would be varying results between the brands of toothpaste used, so we only used 2 in this experiment. 

The results were surprising.

Background of the experiment

Eggshells were used because they have the same chemical composition as our tooth enamel, making them react similarly with chemicals.

Bleach represents the acid that damage our teeth. According to Healthline.com, one of the main causes of enamel erosion are acids found in the foods and liquids we consume. 

Saliva constantly neutralises acid in our mouth to protect our teeth. But eating too much acidic food and drink, and not properly brushing our teeth can cause the outer layer of enamel to degrade over time.

You can refer to the article mentioned above for examples of food that can cause enamel erosion.

Equipment used in the experiment

The clear disposable cups we used didn't come with lids. Demi had to transfer the eggshells and bleach to another container with a lid so she could bring them to school for presentation. 

If you need to present too, save yourself the hassle and get yourself disposable cups with lids online.


Demi prepared 3 disposable cups and labelled each as follows:

  • Oral B
  • Atomy
  • None

She then put equal amount of bleach in each cups.

Bleach on cups experiment

Then Demi started brushing one of the eggshells with ATOMY toothpaste. She left the toothpaste on before immersing the eggshell into the acid. 

Then she brushed the other eggshell with Oral B. As with the ATOMY, she left the toothpaste on and then immersed the eggshell on the bleach.

Finally, she added the eggshell without the toothpaste in the acid last.

All eggshells were immersed in bleach by 19:40 PM.


After less than 5 minutes, the eggshell without any toothpaste on was already crumbling. When we looked, the eggshell has completely disintegrated.

We left all eggshells overnight and checked again after 24 hours. 

The objective of the experiment has been achieved. Clearly, brushing our teeth is important in reducing the effect of acid on our teeth enamel. 

We thought that there wouldn't be a difference in the results of either eggshells with ATOMY or Oral B. Or if there would be, we thought that the eggshell with Oral B would hold its shape better because the toothpaste was marketed as good for "gum care and enamel restore."

Meanwhile, ATOMY is marketed as a toothpaste with "propolis" and "green tea extract." Meaning, its antibacterial properties help to prevent bad breath. While this feature had been proven by actual users, in this experiment, it wasn't very relevant.

Photo below was after 24 hours

After 24 hours, both eggshells with Oral B and ATOMY held their form. Surprisingly, there were less broken pieces found in the eggshell with ATOMY than the eggshell with Oral B.

There has been differences in the photo because we had to place the cups somewhere safer. Initially, we held the experiment on the kitchen counter but had to move the cups in a corner where it's not accessible as bleach is a dangerous substance.

As such, the lighting also changed but in the photo below, it is clear that the eggshell without the toothpaste has crumbled to the ground. The eggshell with Oral B had decreased its size dramatically and you can see that there were more broken pieces at the bottom. 

Meanwhile, the eggshell with ATOMY toothpaste held its shape the best among the three.


Demi's experiment had been a good eye-opener about the importance of brushing our teeth as well as choosing a better diet to keep our teeth healthy. We do not disregard other factors, of course, such as genetics and lifestyle.

Although it was not part of Demi's hypothesis in the beginning, it appeared that choosing a brand of toothpaste is also important if we want to keep our teeth healthy.

Despite the fact that we already use ATOMY toothpaste, this experiment only made me more confident and thankful that I made the right choice. 😁

PS: Feel free to re-create this experiment for a school project, for marketing presentation, or just for fun with the kids. Just be very careful in using bleach. Use gloves and mask!

PPS: If you want to shift your brand to ATOMY, message to buy from me. Thanks in advance! 💗

PPPS: The toothbrush used here is also ATOMY. It's soft bristles contain fine gold dust for antibacterial properties, keeping your brush clean 24/7. If you're tired of getting moulds on your toothbrush handle, go for this one. For the technology used to make quality toothbrush like this, their price is very cheap. If this convinced you to change brands, message to buy from me too hehehe. Thanks in advance again! 💗

Winter Interactive Cards - Sliding and Floating Stamped Images

Tuesday, June 15, 2021

It's good to finally have the time to make this post - introducing, my interactive winter-themed cards for this year! I got these cute stamp set after winter last year and I had to wait almost a whole year to finally use them. 

This year, the cold came really early. In fact, we hardly complained about the heat during summer either. It's a comparatively colder year in 2021. As early as the last weeks of May, I was already brainstorming and voila!

Winter interactive card ideas
Foxy on his sled on a couple of cards (using slider technique) and Twinnie Penguins bobbing on another card (using floating image technique by Jennifer McGuire).

The stamp set features a fox on a sled, a penguin with scarf and some really nice sentiments. They make cold look cute.

But unlike Elsa though, I don't like the cold, it bothers me a lot hahaha. Still, I find winter to be a beautiful season with it's glistening snow and tinkling icicles. I wish I was more like cute Foxy and Penguin so I could enjoy the snow too!

I looked at my stash to see how I can make these cards. You see, I try to limit my craft supplies spending now. Whenever I have a project in mind, I make sure that I can do it with what I have on hand.

Creating a snowy background cardmaking

Fortunately, I have 3 shades of blue inks and my ever handy brush makeup applicator to create the background. Then, using white poster paint ($2 from Kmart) and a fine point paint brush, I added the snowfall effect. Just looking at the background already makes me shiver in cold! ⛄

Snowy background cardmaking

I can't not use cute Penguin either. With one of its feet in the air, it looks like it's dancing so why not make 2 cute dancing Penguins on the snow? 

To make them "dance," I used the floating image technique by Jennifer McGuire

Here they are, dancing with their Happy Feet!

Winter has just started and God willing, I will come up with more winter-themed cards to make while the snowy season lasts. 😄Happy winter!

My Birthday Wish

Friday, June 11, 2021

When you're almost 40 and you're running a household with 3 children at different life stages (1 teen, 1 preteen and 1 toddler, all GIRLS!), your own birthday is nothing more than a day to break from the daily routine. So instead of the usual 7-hour work, I took a half rec leave - to run errands and then treat the family out.

I'm not complaining. In fact, the mere messages of family, friends and friends of friends who greeted me on Facebook were more than enough to make me happy - I'm very easy to please. But yesterday was filled with surprises and I can't say thank you enough to everyone and most especially to God, for making my day a happy one.

First of all, I woke up to see my husband's gift right on top of my office desk. Although I knew what's inside (they're specific requests so this one wasn't a surprise haha), I couldn't wait to get my hands on them. It was distracting me while I got ready to go to office hehehe.

Mommy book and bluetooth earphones (for audio books and podcasts)

Then, at work, my boss brought a box of Krispy Kreme donuts for the team. We usually don't bring food on team meetings so it felt a bit festive to have some sweets while discussing. 😊

After the meeting, I went to lunch with 2 of my closest friends at work. Both of them had surprised me with gifts too. 

My lovely friends 💗

When you're old, you get to understand that people's time are valuable and so the mere fact that they spent time to have lunch with me was more than enough to make me gratified. But to have surprised me was just beyond what I prayed for. Thanks be to God to be blessed with such good friends in my life.

Then I received greetings from sis Karen and a photo of ube cake she baked (my favourite ube cake!) and a chocolate bouquet. She hand delivered the gifts at home and I just couldn't wait to see them in person.

She has always been sweet like that, which is admirable considering that we have the same birthdays. Of course, I have something for her too, but the day just went crazy yesterday that I wasn't able to drop the gift off to her house.

As I have said, I didn't really plan to make this day special. In fact, after lunch with my friends, I rushed to meet my husband (and our baby tagging along) at Blacktown, so I could organise Daisy's enrolment for High School.

After the enrolment, we took the opportunity to run some more errands (buy food stock, canvas for carseat upgrade, etc) while we waited for the girls to finish school. When the girls arrived, they were both hungry and tired so we had to get them some snacks while we did more groceries and finally took them to dinner - the only part that's related to my birthday celebration hahaha.

By the time we're finished, it was 7:30pm. As usual, it was a day packed with errands and running after Darla. 😄 Duties never end when you're an adult 😂 but it was a good kind of busy day. A contented kind of tired.

I looked at the messages from various people, the gifts before me, the memories of this day filled with blessings and lingered on to the good feelings inside. 

When you're almost 40, and a parent, and working and busy, birthdays are the perfect time to stop a few minutes, catch your breath, and remind yourself that if you have food on the table, a few people who care, a job you can keep, your family and loved ones are kept well/safe and just enough money to live by, then you are already blessed beyond words.

lAll I can say is thanks be to God for another year of witnessing His love and care. I've had more than enough share of happiness for my birthday today, I don't think I'd want anything else for myself anymore.

And so, as I blow out the proverbial candle on my cake, my wish goes out to everyone else out there - those who are in pain, those who are suffering, those who are in need, those who are in sorrow. Whatever it is they wish for in their heart, then that is my also my birthday wish.

Why I Bought A Retro Game Console For My Kids

Tuesday, May 25, 2021

This mini retro game console arrived by post today! I felt really excited while we took turns playing. I and my husband felt like Jedis showing these children how it's done. 😎🤺🎮  Old school? Yes! And I am not ashamed of it hehe.

Retro Game Console Australia based
The retro game console or better known as Family Computer to the retro parent like me 🤣

5 Reasons Why I Prefer Retro Games VS Modern Games

When the Retro Game Console arrived, I couldn't wait to try it out right away. After my husband had set it up, I felt so excited and hopeful already. Just manage your expectations though, as the graphics aren’t half as good as the games nowadays. But just seeing Mario on the screen this morning made my heart jump for joy. 

As I was hit by waves of nostalgia, I realised that I wanted my kids to experience this happy part of my childhood too. I was more convinced than ever that I made the right decision for choosing the retro game console over the modern game consoles. Here’s why:

  1. Retro game console is relatively easier to set up.

It’s basically plug and play. I usually leave the technical side of things to my husband but he had the console set up in no time.

As I have mentioned, we haven't tried Xbox or any of the modern game consoles but I heard that there are more complexities in them such as requiring wifi and updates. Sorry to say this, but I might not have the patience to learn these things which will obviously kill the excitement a bit.

  1. Retro games are familiar and easier to teach and navigate

I know that kids nowadays are fast learners so they will definitely learn how to play the retro games in no time. The problem is, I and my husband might not cope up with the opposite hehehe. Which means, when we play as a family, then we won’t be on the same grounds.

The kids might sense this and subsequently, might not be keen to join their parents anymore.

  1. Retro games are more family oriented

Retro games weren’t called Family Computer for no reason. Because the console isn’t wifi supported, you’re most likely to play with your family side by side with a retro game console.

Modern game consoles and most games and apps on the other hand, were designed for online gaming. As I have mentioned previously, I am not comfortable with my children playing online with strangers because of the dangers lurking in the internet.

Call me a paranoid parent, I don’t care. But the truth is, we didn’t have to deal with these dangers as a child. I don’t see why I shouldn’t protect my children from these risks as well.

  1. Retro games have more interesting backstories

I didn’t realise this but if I have to compare the games we played before vs the games children play now, retro games were more creative when it comes to stories and characters.

Take Mario Brothers, for example. The main characters as well as the villains may look cute but the game is actually about a noble love story of a guy trying to rescue a Princess from the hands of a turtle-and-dragon-cross-bred king.

But I think what stands out is that the games before always had the good side trying to defeat the bad side unlike the violent ones that are rampant nowadays.

  1. The final point, it was cheaper and smaller

When I saw this ad, I was really impressed to see how cheap the game console was – and free shipping Australia-wide too!

The unit was very small too, so it’s easier to store away when you’re done. Again, because it is less complex, there’s not a lot of cables and parts either.

Why I Bought The Mini Retro Game Console 

Earlier last year, I posted about my problem controlling my kids from too much screen time. Although I have found ways to limit their use of gadgets, such as giving them other activities and establishing screen time rules, I still think of ways up to this day how to get their hands off their gadgets as much as possible. 

If I could totally get them off their phones and iPads, that would be best. These smart phones and tablets pose as a huge distraction especially when the kids get accustomed to social media. Chatting with their peers eat up valuable time that should otherwise be spent for reading or studying. Not to mention the great risk of these children being exposed to predators who could easily disguise behind fake accounts. 

However it's not all bad and ugly for gadgets. Giving them access to these technological advances is also a necessity these days. 

For example, my daughter hones her artistic skills in digital drawing and learns about entrepreneurship by using her iPad. They also use their gadgets to research about lessons in school. 

But as parents, who are also busy with work, a toddler and other responsibilities, I and my husband can't always control their activities online. That is why if there are ways to limit their access to gadgets, then I go for it. 

Gaming and gadgets

One of the challenges in successfully detoxing the kids from their gadgets is gaming. I tried talking to my girls about taking away their phones and iPads, and while they were more accepting to let go of their Social Media (which they shouldn’t even have in the first place), they are more reluctant to give up playing games.

I can totally understand them with this one because video games also played a big part in making my childhood happy and memorable. I know the gaming world has changed so much many, many years after, so it took me a long time to decide which one to get for the kids. There’s Xbox, PlayStation and Nintendo Switch but I have no idea how each one differs as I have not tried any of them, not even once.

Then I found this Mini Retro Game Console in an ad. Out of impulse, I decided it’s about time, added it to cart, checked out and crossed my fingers for the best.

I remember my own childhood days when we'd all gather in the living room around the Family Computer/Retro Game Console. Each of us had our own favourite games: Mom was best at Bomber Man, Dad at F1 Race. 

My eldest brother was the best at Punch Out while my other brother, who was probably the best gamer, excelled in Rock Man as well as a lot of other games I could not recall anymore.

Those were such fun times. We were connected and cheer on each other to win (or otherwise lose when we're angry haha). But those were memories etched in my mind forever. I have a lot of hopes that this Retro Game Console would also be an instrument to more family times for us, and I just can't wait to play and beat my husband and 2 girls lol!
