This is probably my 4 year olds favourite home experiment to date. It is a great activity for young children as it is quite simple, mess free and fun to watch.

Using the funnel pour the bicarbonate of Soda into the balloon.

Carefully place the balloon on top of the bottle making sure you don’t empty any of the bicarbonate of Soda into it.

Place the bottle onto a tray.

Get your child to lift up the balloon to mix the powder and liquid together.

Sit and watch as the ghost balloon blow up.

Watch the video below to see how it works.

Science behind the experiment :

Mixing bicarbonate of soda with vinegar causes a reaction which then produces carbon dioxide gas. The gas created can not escape from the bottle because of the balloon. As more gas is made, the bigger the balloon grows.
