Inventor's Lab MAKE A BOTTLE SQUIRT GUN

Want to make a powerful squirt gun that your friends will never suspect? It’s simple. You just need some air pressure.

MATERIALS

First, use the tack or needle to poke a hole in the center of the water bottle cap. Then fill the bottle with water. Screw the cap tightly onto the water bottle.

Next, insert the needle of the bicycle pump into the hole in the lid and pump air into the bottle. This will add pressure to the bottle and make it squirt farther. Stop pumping when you feel the bottle is full.

Now you have a squirt gun that looks like a regular water bottle. You just have to press your thumb on the bottle, and it will squirt your friends and family.
