I took a little break because I was busy with school. Yes Grade 2 is hard work but I’m back with another cool experiment for you. This is an easy one that will surprise you.

All you need are the following

  • Empty bottle (Soda or water bottle works fine)
  • Water
  • A piece of paper towel

Instructions:

  1. Fill your bottle with 3/4 water
  2. Using a damp piece of paper towel, place it on the bottle’s mouth and tear any excess off so that you are left with what looks like a cap.
  3. Flip the bottle over and BOOM, nothing happened. No splash. The water didn’t come rushing out.

The reason is because Gravity pushes the water down but thanks to air pressure and surface tension, the water doesn’t go anywhere.
