During this time, we are constantly trying to figure out ways to entertain our children. Here’s a really easy science experiment you can do with your child, using things that you would have lying around at home. Watching their excitement as the egg yolk magically jumps into the bottle is priceless!

Eggs are one of the most versatile objects for science experiments. Here’s a very easy one. The two main things you need is an egg and a plastic bottle.

Things Required:

  • 2 raw eggs
  • 4 plates/ Bowls
  • 1 teaspoon
  • Plastic bottle (Bisleri or coke bottle)


Crack one egg on a plate or in a bowl. Ask your child if they think that you can take only the yolk and put it into the next bowl. Give them a teaspoon and ask them if they want to try and take the yolk and put it into the bowl.

The egg yolk will break.

It will invariably become a mess. But let your child keep trying to take the yolk with the teaspoon.

Now tell them that you will show them some magic. Tell them that you will transfer the yolk from one bowl to the other without breaking it.

Crack another egg into a clean bowl. Squeeze a plastic bottle and hold it over the egg yolk.


Slowly release it and watch as the egg yolks gets magically sucked into the bottle!


Once the egg yolk is fully in the bottle it, lift it up and show your child, how only the egg yolk is in the bottle, and the egg white is in the bowl.

Hold the bottle over another clean bowl and slowly squeeze it again. The yolk will fall into the bowl.

Explanation (for preschoolers): When you squeeze the bottle, the air from the bottle comes out (You can let the child put their hand at the mouth of the bottle and feel the air coming out). When you hold the bottle just above the egg yolk and release it, suddenly it has to take air back in, and since the yolk is right next to the mouth of the bottle, it pulls it up into the bottle.
