How to Defy gravity with a water trick

In this tutorial, we learn how to defy gravity with a water trick. First, you will need to fill a cup with water. After this, place a piece of plastic over the top of the cup. After this, push the plastic down, then turn the cup upside down. You will notice that the water does not immediately come out of the cup! Next, place a plastic bag filled with water into water, then bring it out and poke two pencils through, and none of the water will immediately leak out! These are great tricks to show kids and teach them how gravity works with water and air!
