Mel Science Physics :🎈💨 How to Wow your friends with this neat trick!

One of the many pleasures of knowing a little physics is being able to impress your friends and family with some easily available household objects and showing them tricks that are really kinda counter-intuitive!

We think this little magically inflating balloon trick makes for either a great office lunchtime bit of fun or quick and easy homework task to demonstrate to folks around you your knowledge of atmospheric pressure!

All you need to do to create this wonderful experiment is...

Equipment:

1. Glass bottle: Buy here: https://amzn.to/3Hb6jJR
2. Balloons : Buy Here : https://amzn.to/33GE9bL
3. Access to boiling water!...c’mon switch the kettle on!

Method:

1. Pour some boiling water into a glass bottle and wait until the glass warms up. (approx 1-3 mins)
2. Pour out the water and put the balloon on the neck of the bottle.
3. After a while, the balloon will be drawn into the bottle, and then it will inflate!

Explanation

Putting the balloon on the neck of the bottle, you create a closed system. This system has a fixed amount of air and a temperature higher than the ambient temperature. When the glass cools down, the air inside the bottle cools as well. With it, the pressure decreases, becoming lower than atmospheric pressure. Atmospheric pressure “inflates” the balloon into the bottle.

Safety : Take care when handling hot water.
