If you mix cornstarch and water (2 to 1), you will get a suspension that acts like a solid when you put a pressure on it, but then it can flow like a liquid. Perfect for messy play at any age. If you feel creative, add some food...

Classic egg in a bottle experiment turned upside down. We used hard boiled egg, birthday cake candles and a bottle with wide neck.

Don't trust your eyes! If you cannot see it, it doesn't mean that it is not there. When you place a Pyrex stir rod in the vegetable oil, it disappears. The secret here is that vegetable oil has nearly the same index of refraction as...

When Alex played music this way no one could hear it but him. To change the sound he pulled the string a bit tighter or slid hand that was holding the string to change the length of it.

Here’s something that’s really amazing, but it also takes a bit of skill and patience too! How can you pick up a ball with a glass without touching the ball itself? Place the glass over the ball and then start spinning the glass around...

We are exploring friction with this simple science experiment. Max put raw rice inside a bottle and taped it against the table, the rice settled, reducing air pockets between each grain. So much so that when Max pushed a wooden spoon...

This experiment proves that eggshells are not as fragile as one might think. Let's see how many eggs will break when Max stands on them.

Here is a simple DIY demonstration of centrifugal force. This physics experiment shows how two ping pong balls move away from the centre when we start spinning.

In this simple presentation, we see how siphons work. I asked Alex and Max to pay attention and tell me at what level should be water so that it starts going through the straw. So they did, had fun and learned something new.
