Empty bottle and air pressure

SpottingScience is a project at the university of graz

Want to see what air pressure can do?
Then use your empty plastic beverage bottle for an experiment!

Empty your plastic drinks bottle before the descent. Make sure the bottle isn’t crushed.
Now close the bottle. You can put it in your backpack or just hold it in your hand.

Look at the bottle in the valley station. If you held it in your hand while driving, you can already notice a change.

Curious about the result?

By moving the slider you can see a before and after comparison. The first picture shows the bottle on the mountain, the second picture shows the bottle in the valley.
