Balloon Air Pressure Magic
Warning all grownups: get your sense of humor ready for this science experiment, which demonstrates fundamental physics of air pressure. You can do this in a lab, of course, or with technical worksheets, but we love this goofy “magic” trick with a kid and a grownup…and an audience, too, if you dare.
What You Need:
- 2 plastic drink bottles, 1-2 liters in size, clean and dry
