Fun with dry ice... LOTS of fun with dry ice. (from the Usenet.)
|
|
---------------------------------------------
|
|
|
|
|
|
There is no standard formula for a dry ice bomb, however a generic form is
|
|
as follows:
|
|
|
|
Take a 2-liter soda bottle, empty it completely, then add about 3/4 Lb of
|
|
Dry Ice (crushed works best) and (optional) a quantity of water.
|
|
|
|
Depending on the condition of the bottle, the weather, and the amount and
|
|
temperature of the bottle the bomb will go off in 30 seconds - 5 minutes.
|
|
Without any water added, the 2-liter bottles will go often in 3-7 minutes if
|
|
dropped into a warm river, and in 45 minutes to 1 1/2 hours in open air.
|
|
|
|
The explosion sounds equivalent to an M-100. _Plastic_ 16 oz. soda bottles
|
|
and 1 liter bottles work almost as well as do the 2-liters, however glass
|
|
bottles aren't nearly as loud, and can produce dangerous shrapnel.
|
|
|
|
Remember, these are LOUD! A classmate of mine set up 10 bottles
|
|
in a nearby park without adding water. After the first two went off (there
|
|
was about 10 minutes between explosions) the Police arrived and spent the
|
|
next hour trying to find the guy who they thought was setting off M-100's
|
|
all around them...

USES FOR DRY ICE
|
|
|
|
Time Bombs:
|
|
|
|
1. Get a small plastic container with lid (we used the small plastic cans
|
|
that hold the coaters used for large-format Polaroid film). A film canister
|
|
would probably work; the key is, it should seal tightly and take a fair
|
|
amount of effort to open).
|
|
Place a chunk of dry ice in the can, put on the lid without quite
|
|
sealing it. Put the assembled bomb in your pocket, or behind your back.
|
|
Approach the mark and engage in normal conversation. When his attention
|
|
is drawn away, quickly seal the lid on the bomb, deposit it somewhere
|
|
within a few feet of the mark, out of obvious sight, then leave.
|
|
Depending on variables (you'll want to experiment first), you'll hear a
|
|
loud "pop" and an even louder "Aarrggghhh!" within a minute, when the CO2
|
|
pressure becomes sufficient to blow off the lid.
|
|
In a cluttered lab, this is doubly nasty because the mark will proabably
|
|
never figure out what made the noise.
|
|
|
|
2. Put 2-3 inches of water in a 2-liter plastic pop bottle. Put in as many
|
|
chunks of dry ice as possible before the smoke gets too thick. Screw on the
|
|
cap, place in an appropriate area, and run like hell. After about a minute
|
|
(your mileage may vary), a huge explosion will result, spraying water
|
|
everywhere, along with what's left of the 2-liter bottle.
|
|
|
|
More things to do with Dry Ice:
|
|
|
|
Has anyone ever thrown dry ice into a public pool? As long as you chuck it
|
|
into the bottom of the deep end, it's safe, and it's really impressive if the
|
|
water is warm enough
|
|
|
|
"Fun stuff. It SCREAMS when it comes into contact with metal..."
|
|
"You can safely hold a small piece of dry ice in your mouth if you
|
|
KEEP IT MOVING CONSTANTLY. It looks like you're smoking or on fire."
|
|
|
|
Editor's Note: Dry ice can be a lot of fun, but be forewarned:
|
|
|
|
Using anything but plastic to contain dry ice bombs is suicidal. Dry ice
|
|
is more dangerous than TNT, because it's extremely unpredictable. Even a
|
|
2-liter bottle can produce some nasty shrapnel: One source tells me that he
|
|
caused an explosion with a 2-liter bottle that destroyed a metal garbage can.
|
|
In addition, it is rumored that several kids have been killed by shards of
|
|
glass resulting from the use of a glass bottle. For some reason, dry ice bombs
|
|
have become very popular in the state of Utah. As a result, dry ice bombs have
|
|
been classified as infernal devices, and possession is a criminal offense.
