This was all made using equipment bought at the SWAP 100 hour challenge. On the left is a plastic jug with a lid that clamps on the top. In the middle is a short length of tubing, and on the right is a small hand pump.

I had to modify the jug by drilling a hole in the side, and screwing in a tubing connector. The hand pump already had a connector for tubing.



Here is a video of a peep inside the chamber. You can see it grow as the air is pumped out of the jug, and when the air is let back in you can see the peep shrivel up.

<p>I am building an advanced version of this. My pump comes with 2 23 inch sections of vacuum hose and some fittings. I will splice them together and use hose clamps. To release the vacuum, use the needle valve. The chamber will be made from a canning jar and it will use solder and JB Weld </p>

Flagged as incomplete. No explanation, no actual instructions, no nothing. Just a picture.
Yeah, it's my first ever post, I'm stilling trying to figure out how to 'make' an instructable. I'll be fixing it this week
Ah! Click the [b]Submit[/b] in the upper right corner of any page. Choose the &quot;Step-by-step&quot; Instructable. It should walk you through creating an Introduction, and then you can add steps as with all the details of your build. The idea is that someone else (without you around to help them :-), should be able to follow what you write and build the project themselves. Good luck, and welcome!
