Picture of Easy Air Pump Bottle

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
  • Balloon
  • Tape
  • Scissors
  • Drill

Good Luck!

Step 1: Making the Membrane

Picture of 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.

Clever idea. Any idea what kind of pressure you were able to get.

I didn't measure the pressure.. 1.5 bar ?

Genius membrane, to avoid the air going back into the bottle :)
