In this experiment we are going to find out how we can squash a bottle using just water.
Please subscribe to this website using the newsletter below, and you can chat me up using the red little icon below or you can bring up experiments suggestions.
Alright the things you need for this experiment are as follows
- An empty plastic bottle with the stopper (cover)
- Hot water
- Fill the bottle with hot water
- After a few seconds, remove the water from the bottle and cover the bottle immediately.
If you did the experiment well, you will see the bottle flatten lenght ways , as if two hands were squeezing it
Because.....
......the air inside the bottle, expanded because of the heat, has a lower pressure than the air on the outside.
It is the pressure of the air outside that squashes the bottle.
