Fun Science Experiment: Fizzle Rocks

Fun Science Experiment: Fizzle Rocks

Since the start of this year, we have been faithfully going to the library every week. Yes, every week! It has become such a habit that if we ever skipped a week without popping over to the library, smarties will complain especially gor gor. He’s so into reading that he can 3-4 books a day. He also love working on Science experiments at home so he has been borrowing Science experiments related books to explore.

Smarties love bath bombs and one of the experiments teaches us how to make something really similar to it. So what is bath bombs? They are actually hard-packed mixtures of dry ingredients which fizzles when in contact with water. They are used to add essential oils, scent, bubbles and color to bathwater. We are not making bath bombs but fizzle rocks. It is very similar to bath bombs except that it has to be in contact with vinegar instead of water in order to fizzle. Also, we definitely are not using it to bathe!

Can’t wait to know what exactly it is and how to make? Here are the ingredients required:
– vinegar
– baking soda
– mixing bowl
– toys (preferably small toys)
– food colouring
– spoon
– water
– plate

And here are the steps:
– mix baking soda and water to a paste that you can mould
– add in food colouring of your choice and stir again

– place the toy into the paste and “wrap” it up to a ball

– leave the ball overnight for it to dry

Once the fizzle rocks are dry, you can start playing with it! Pour vinegar into the mixing bowl or any other bowls of your choice. Place the fizzle rocks into the bowl of vinegar and watch magic happens! It’s really fun and exciting to watch the rocks fizzle, disappearing and having to see your toy popping up. Smarties enjoyed the whole process of the experiment.

What have they learn from this experiment?
– they get to learn and observe the chemical reaction between baking soda and vinegar and how carbon dioxide escapes the solution as bubbles.
– it trains their focus by paying attention to every single steps that they made
– it trains their motor skills where they stir, scoop and mould their toys into the paste and into a ball
– it encourages them to express their ideas and communication among them

What do we do with the solution?
– well, mommy here use it for cleaning purposes. Nothing is wasted.

So why wait? Start making fizzle rocks now! Here’s a video with smarties guiding you on how to prepare for the experiment, all the way to getting your little toys back! Enjoy!
