How To Make a Fountain in a Bottle

In this video, you will learn how to make a stunning fountain with plastic bottle! In a hot bottle, the air expands and some of it is even forced out of the bottle entirely. As the air cools in the closed bottle, the pressure in the bottle decreases, and the external atmospheric pressure begins to push water into the tube. This creates a fountain! This fountain can help you come to terms with it and find peace.
