Coke bomb prank video

[Nohr]

A new breakthrough in Coke Bomb Technology.

 

[Minerva]

Oh the Mentos trick is well known.

My brother is guilty of that. Dry ice bombs going off at the bottom of the pool create shockwaves like a tiny earthquake but that's another story.

Check out these nerds.

I've seen the coke + mentos thing before but never as a prank like that.

Got a vid of the dry ice bombs?

Dry ice pellets + warm water + coke bottle. Run like hell after screwing lid on tight!

Remember at 90F the pressure can theoretically reach 1050 psig! I don't know what the average rupture pressure of your typical 2l coke bottle is but even if it's a few hundred psig the sudden release of energy is violent and can break fingers and send flying plastic shrapnel in all directions for a few yards. Not as dangerous as a pipe bomb but not something you want to put under someone's bed either.
Although sometimes I wouldn't mind a medicine bottle size one in my brother's computer.

So you put some warm water in a 2L coke bottle that is weighted down, drop in some pellets, screw on cap and drop in pool?

 

[Minerva]

Yeah that's about it.

I'd love to see someone do it in an above ground pool. :Q

 

[djheater]

Even in-ground, I imagine that it could exacerbate a stress condition and cause a crack...



Only do it in other people's pools :evil:

 

[BrunoPuntzJones]

Neat looking with the pool thing, but seems like a good way to break the concrete underneath...

 

[naldo]

dry ice bombs are great fun. Burying them in the ground before you screw the top on is cool too if you can get a good ice-water ratio for maximum boom. It helps if you duct tape aroun the cap aswell (since alot of times the cap just blows off prematurely and not enough pressure build up, but it can be dangerous if you take too long.

 

[Minerva]

I don't think it will hurt the pool. The vibration is like a heavy truck going down the road. It's quite a shock but a good concrete pool should have no problem with it. I wouldn't do it all day though.

That's what the dock is for. Don't want to give the fishermen the wrong idea as they might want to try something stupid.

Mythbusters tested plastic bottles once. I forget the exact figure, but I think it was around 150psi for two liters, significantly less for those large water jugs that go on a stand..

 

[Chronoshock]

When I did coke bombs, I used liquid nitrogen. Just pour some into the bottom of an empty bottle, cap it and hurl into a river

Hmmm why do I have to delete all this stuff quoted? Can this BBS software get upgraded to the 21st century please?

Anyway, our shop air is 250 psig. :Q I'm going to ask my brother to do an experiment!

LN2 is so cold it would embrittle the bottle and weaken it considerably.

Zinc + HCl generates H with a good pressure. If one vialed each inside one of those large glass vinegar jars and epoxy'd the cap on solid and gave it a good shake I'd imagine the boom would be nice. Glass shards at half the speed of sound cut like a flechette so it's not one to do near the pool!

I do dry ice bombs every year instead of fire works for the 4th of July! It's a lot cheaper and *MUCH* louder.

Louder? Hmmm perhaps you're not getting the right stuff.

I know a guy who had one go off near him and he is now deaf in one ear.

When I was a kid we used draino and aluminum foil in 2 liter bottles, fantastic stuff (the dry draino, not the liquid).

I remember doing this, but it was with liquid. I seem to recall finding out about it in the Anarchist's Cookbook.

Chlorine and alcohol? Yeah that's really smart. :roll: That's probably pool chlorine granules which is lithium hyppochlorite. It has a lot of free cl when reduced. I've seen what happens when the wrong oxidizers get mixed. It goes BOOM like a tube filled with halkf a kilo of flash, eminates pink flames like Satan himself is rising out of the skimmer. Dangerous stuff!

Lukewarm water and dry ice pellets won't raise the pressure that fast and only a fool will go chase it down and try to make it break. Break out the ole Mossberg and shoot the damn thing!

It would be neat to make a manifold with solenoids where the bottles could be rapidly filled with nitrogen from a cylinder with the regulator set at 1kpsig or so. Push the button and hear a hiss then boom! Use bottles partially filled with water and different sized bottles and a midi sequencer and I bet you could play a tune!

Go to a nearby lake, and go fishing. Drop the depth charges, and wait for the stunned fish to float to the surface.

I don't know why they didn't expect that result. The big water jugs are meant to hold unpressurized water, that's it. Soda bottles are designed to hold in a fair amount of pressure; it stands to reason that they'd be the better pressure vessels.


What else is fun - some of that "canned air" for cleaning out computers, and small film canisters. Hold the can upside down, spray some of the liquid into the canister, cap it, wrap your hand around the base to warm the liquid, and shake. The cap will shoot off, and it should make a nice pop. I don't think it works well with the black and gray canisters, they don't seal well enough. There's another kind (maybe Fujifilm?) that gives a better seal.

What might this do?

Sounds like a good followup to those guys doing their elaborate Mentos + Coke displays. And maybe do it really slow, then speed up the playback. That way the booms will be a higher pitch, who knows what they'd sound like then.
