Wanna make big loud bangs "safely"?

I think you could loose a finger, but you definately wouldn't go deaf, I've had one thrown in a car with me before, and I was fine. Pissed, but fine.

uhh where do i get dry ice?

also my friends an i are planning to buy a liquid nitro container...now thatll be fun

[MrVicchio]

I would buy it at H-E-B but a hunting store might carry some, for packing your kills. Make a few calls or do a web search, its not that heard to get a hold of.

Also. 2 liters, Vs 20oz bottles... 20 oz bottles RULE. MUCH louder, the plastic is thicker so it takes more gas to Pop.

You don't HAVE to use wateer, it just accelerates the process and allows you to use less Ice. You don't use water and its slower, sometimes the plastic will bubble first..

I put those disclaimers in, in case some idiot were to hold one in his hand by his ear. MMMKKAY? I have watched one of those detonating, and you can see the "blast" wave of air condensing its awesome. The two liters spolit too fast.

The water wouldn't do jack. It's the pressure building up from the dry ice subliming that creates the explosion.

Hmmm... So wouldn't a PVC pipe work great if you got caps, and PVC-cemented them on with the dry ice/water mixture in it? If you were to fill the tube 80% full with dry ice I wonder if it could create enough pressure to blow out 1/8th PVC...

If so, I very likely have a new hobby... That should be loud enough to sound like a cannon going off!

[Rayder]

Don't put too much in or it won't work as well.

Any time from 2minutes to 2 hours everyone in the complex would jump out of their seats. Always scared the shit out of me too.

wonder if it's as fun as a potato gun...

[Fenrys]

I use pool acid and strips of aluminum foil inside plastic bottles.

The reaction happens much faster - once the foil goes in, you have about 30-60sec to cap it and throw it.

[Rayder]

pool acid?

[Fenrys]

Yeah, it usualy comes in 1 gallon jugs and is kept next to the cloriene. Wal-mart carries it.

[Rayder]

Whats it do

I don't think it would do anything. PVC is pretty damn strong, I doubt it would blow.

The water serves as an accelerant to the dry ice turning back into gas. Like Vic said, if you don't use water, sometime the ice goes right through the bottle.
