Smarties love science. Whenever they have their hands on youtube, they will search for science experiments and watch how people conduct the experiments or doing research. They watched so many of the shows that they requested to have their own science experiment show too! Of course, mummy will be uber glad to be able to help them video record their very first show.
Smarties were pretty nervous and their speech wasn’t really consistent, and pardon my video skill, as I have some issues getting the right focus. Nonetheless, a very good try on their very first attempt on the video!
We did a very simple experiment, without much setup required. All you need is just:
– a glass of fresh water
– a glass of salt water and
– 2 eggs (you can use 1 egg too if you don’t have 2. Just need to “reuse” the egg)
Why this experiment?
Smarties wondered why the same object can float or sink in different types of water? Well, that got to do with the *density of the object and the water surrounding it. When the water is denser than the object, the object will float. In order to make the water denser, we added salt to it. Now, let’s explore with the eggs!
Psst…in order for the egg to float up high, you need lots of salt added to the water. Go ahead and try with different amount of salt in the water and see how the egg floats in it. It’s really fun because seeing is believing!
*density = thickness or compactness of a substance
Your kids are so cute! I should get my kids to watch science experiments rather than cartoons too. Any video channels to recommend?
We don’t stick to one channel… but most of the time the HooplakidzLab will turn up when we do search for science experiements. You can check out their channel 😉
I am going to do this experiment with G. He’s been getting really interested in science lately after the grape and orange: which-one-will-float they did in school.

Yes… is fun, easy to prepare as most of the items can be easily found at home, and best of all easy to setup! In fact, not much set up required… 😉
wow this is really pretty fun! Just a thought though… can you still eat the egg that has been soaked in salt water? Will salt enter through the shell, making the egg salty? :p
We ate the egg. It didn’t get into the egg though, maybe because we didn’t really soak it in the salt water for long. The egg is still edible 🙂
At most become salted egg, now that’s IN thing right? hahaha
Haha.. Salted egg I like! A practical fun experiment that need not much preparation, super do-able!
Hahah…yes!
Your kids are adorable and that candidness 🙂 my little one is too young to appreciate but some day some day we’ll have a go at it.
Thank you, Adeline. Soon your little one will be able to appreciate it 🙂 Time flies when you are with little one.
haha your kids are so cute and enthu about doing the video! Love their voracity for learning. I think it’s great that you do these little experiments with them. I admire your perserverance! I tried but these days, just too little mental capacity to even do some activities with them!
Thanks for the kind words! Is not easy when we just started out, now is like a routine thingy. I believe you can too if you want! Jia you!
OK! Time for the experience with bubba! Thanks for sharing!
Welcome! 🙂
This reminds me of an experiment my kids did using eggs and vinegar. I must write it up.
By the way, your boy did a lovely job of presenting! It’s tough work, I know.
Yes yes….go write up on it ☺️
Thank you Debs G!
I think theres something abt how eggs which dont float are rotten too!
Haha..ya…that will be another test…
