This water bottle with holes experiment can be used to demonstrate the influence of air pressure and surface tension, or you can use it as a great prank on your friends too!

This is a super fun and easy experiment to do at home with just a few simple supplies:

Water bottle
Water
A Sharp Pin
Large Pan
Funnel

The science behind this fun trick:

Believe it or not, the surface tension of water molecules actually allows water molecules to bond together enough to help keep the water from leaking out of the holes in the bottle.

With the help of the surface tension, and the difference of air pressure outside of the bottle and inside the bottle is why the water does not leak out of the bottle.
