In this project I’ll show you how to make a easy air pump from a plastic bottle.
Things you'll need:
- Small plastic bottle
Step 1: Making the Membrane
Drill a 8 mm hole in the bottle cap. Then you cut a piece out of the balloon and sticking it with three pieces of tape over the hole. On one side of the piece of balloon remains open.
Step 2: Air Input
Easy: drill an 8 millimeter hole in the side of the bottle.
Step 3: Ready!
The air pump is ready! Put a balloon over the cap and squeeze the bottle with your finger on the hole. The piece of balloon on the cap is now acting as a membrane, all air goes into the balloon and can’t get out of it.
Good luck and see you soon! New Pew.
