DIY Drink Dispenser | Air Pressure Bottle Experiment

Check out this awesome DIY drink dispenser for your next get-together, or you can use it as a fun learning activity to teach kids about air pressure!

This air pressure bottle experiment is super easy to make at home with your kids and the best part is that you can do the experiment over and over again!

How does this balloon-powered drink dispenser work!?

The higher pressure inside the bottle is created by the balloon air rushing into the bottle. The high pressure in the bottle then tries to escape to the lower pressure outside and pushes water through the straw!

The water stops coming out of the straw when the balloon neck is pinched because the air pressure becomes equal inside and outside of the bottle and the forces are balanced.
