where do you get dry ice from?

Put your damp ice in a low (175°F) oven for 45 minutes. That should dry it out.
Another method is to empty ice onto a cookie sheet, then under black light, use your hair drier on it's lowest setting for 20 minutes. You run the risk of burning your ice if the setting is too high.
You should also be sure that the area is well ventilated as the process will give off hydrate molecules which can cause death if breathed in sufficient quantities.

i hear you can use a can of dust away (compressed air) and hold it upside down, the aerosol (i think) condenses into dry ice...

that's just 'frozen/solid' (dont pick on me for spelling) tri-fluoro-ethelyne. It is much easier to compress into a liquid (for the sake of making pressurized gas at a factory). It's not directly toxic, but it does cause various health problems - and theres no CO2 in it.
it gets colder because of the expansion of a gas (or less pressure on a liquid) causes it to get colder, and 'freeze' into a solid.

ahh...i see....well, then i do know that where i live A) you must be 18 to buy dry ice (b/c sry ice bombs >:) ) and b) its only sold at Rutter's (of course, this is where i live...in PA)

It's good to know you know why they only sell it to adults. Are you responsible enough to get an adult to trust you enough to buy some for you? In that case you're set! If not, then - you probably shouldnt have any :D

exactly...unless your using the dry ice for cool fog effects....but still, maturity and responsiblity are key when handling any material at sub-zero temperatures....

Sub zero temperatures, CO2 bombs, and oxygen displacement causing death in enclosed areas...none are good things :D

no, unless you are using them as tort...i mean, BAD!, VERY BAD!!

You can get it without too much hassle at welding supply, or wholesale food supply shops. Welders use it for all sorts of ...welding... Food shops use it to keep food cold and the off-gassing provides a more sterile environment for shipping. This kind will be more pure and safer for 'food' (not a huge concern, but the welding stuff COULD have been contaminated by a dirty saw...)

A store. Look up 'dry ice' in your local yellow pages.
