In the spirit of theac - homemade devices

[Syrup Beaver]

Found these on another site, simply amazing - yet dangerous as hell to use

The $100 O2 rebreather

http://www.atlimp.com/pend2.htm

And the $3 O2 rebreather

http://www.geocities.com/chickenheadlab/Project021017ThreeDollarRebreather.html

The 'real' units cost well upwards of $5,000 (For good reason of course) but I'm tempted to build one of these suckers for kicks and use it in the pond

I like how both pages say "These may kill you and if they do it's not my fault"

In this country where there's warning labels on soda cans, I'm surprised there isn't more

So what goes in the scrubber canister? Some sort of chemical that absorbs CO2?

Yep, Sofnolime for example

Not a gadget per se' but I do wanna build a water powered rocket.

like one of these:

http://www.lnhs.org/hayhurst/rockets/
http://www.outsideconnection.com/rockets/default.htm

This way I don't have to buy rocket engines from Este's and my son, nephews and I can launch shit w/ only the danger of contusions or plastic shrapnel as opposed to burns, shrapnel and contusions. Still fun less deadly.

Ooh, and a replacement spud gun. We broke ours a long time ago.

I saw that episode of Mythbusters on Sunday

That's wicked cool stuff, I had a couple of water rockets when i was a kid but they were small plastic jobs that got maybe 20-30 ft up

Oh yeah I remember that episode. What inspired this was Make Magazine, where they built a couple of the 2 liter ones, I may have to steal that magazine. I also remember the little red platic ones. I'm thinking a bit bigger though, just to add that element of danger & retardedness to it

The danger and retardedness is 75% of the fun

I've got a giant air compressor....perhaps I'll try this over the summer

The other 25% is when you run away and scream like girls 'cause the rocket falls and launches horizontal or just falls back to earth right where your standing.

I like making dry ice bombs.

[Sp`ange]

yeah, that's not something I'd want to go cheap on.

The $100 O2 rebreather

Okay, Chikken, maybe you can explain this to me. What does the spring in the scrubber do? Does the CO2 absorbing material need to be compressed for some reason?

I'm not intimately familiar with rebreather technology, but I would guess it's just to keep it in place in the housing

Guess this guy didn't have good luck with his home-built toy

[Mean Mr. Mustard]

I tried building my own squeeze-chute, but I couldnt get the tension on the springs right and kept squarshin my "captives".
Ah well, live n learn.

I heard theac roamed the earth millions of years ago, but was killed off by a huge ass meteor

Some hard core creationists believe that this happened only six thousand years ago, and that cavemen had domesticated theac for use as a work animal.

Some hard core creationists believe that this happened only six thousand years ago, and that cavemen had domesticated theac for use as a work animal.

Others believed that after God created the Earth he went down to check things out and was surprised to find theac there waiting for him. He was even more surprised when theac said, in reference to the sun and wind, "Your lighting and audio are all wrong".
