I want to do some "experiments" mostly just crap I'll throw away. I need to make some contraption that will act as an airlock, I'd like to use an empty water bottle for my tests, Disani water bottle to be exact. Anyone have any ideas?

could you just drill a hole in the lid and force some tube down in there? Then you could just run the other end of the tube into a bucket of water.

How about a condom or a balloon?

What kind of experiement do you want to conduct?

It doesn't sound cost effective (time consuming) trying to improve something that is under a dollar already.

My experiment is simply making a starter from my "saved" yeast. It is my first attempt at yeast washing and I want to be sure I did it right. I simply dont have the equipment at hand at the moment. Baloon sounds good....

If you're doing stuff with yeast, you can't afford to have anything but the best. The risk of contamination is incredibly high otherwise.

Plastic airlocks are like $2.00 a piece, so making one seems a bit fruitless. A blow-off tube with the open end dunked in some sanitizing solution makes a great airlock, though.

Wow, everyone relax. I just want to mess around with some yeast and see if my collection methods worked by making a starter that i'm going to THROW AWAY. I dont want to wait 5 days to order airlocks because I dont have any extra. You'd think I killed the pope or something.

Dude, I didn't mean to bash your idea - and I thought the blow-off suggestion was a good one. An even cheaper solution is a piece of aluminum foil folded over the top of your bottle - that's how I make my yeast starters in an Erlenmeyer flask. And if you're just gonna toss the starter anyway, you may consider going without an airlock/cover entirely.
