Make Your Own Water Gun
Help your child design his own super-squirter water cannon! The small hole he makes in a simple soda bottle will turn it into a water squirter at a fraction of the cost of those purchased in toy stores. Believe it or not, this entertaining activity will also teach him about science! When he takes his thumb off the hole, he will encounter the power of air pressure as the air pushes on the rubbery walls of the balloon, causing high-powered water to shoot out of a hole in the bottle cap.
What You Need:
- Nail and hammer (to make holes)
- Plastic soda bottle (the bigger the better)
- Someone willing to get soaked
