Yes
Anyone ever used dry ice in any of there shots? What were the results like and where did you get it from?
 
Shot a magic show last week with dry ice pumping out all night, horrid stuff.

It looks a bit like smoke in that pic. I like when it comes out very thick like a cloud.
 
Thanks for the links. I've found a couple of places that supply but it looks like it's a 10kg minimum order. Just need to find a freezer that goes down to -79c.
 
There are three different theatrical effects which are often confused. The stuff in your shot is smoke. Dry ice is dense and hangs to the floor - smoke looks like smoke - and haze - which is best for pics because it hangs in the air like a mist and shows up light beams in the air - can be quite magical.

You can now get 'dry ice machines' than run on ordinary ice cubes ( a lot of them ) - so cost a LOT less to run but produce the same type of thick white clinging to the floor effect. Check theatre lighting hire companies.
 
Looking at the hire or purchase costs I think I'll just buy a block for £35 and pour it into hot water. Now I just need to think of a good theme to use it with.
 
Got a big enough well insulated ice box to transport and keep it in?

Take great care handling it - you can get very nasty burns.
 
When I worked at Joe's E6 we used liquid nitrogen for agitating the dev tanks. We had massive tanks of the stuff and it had to be kept at a constant pressure for the right agitation. You turned a valve to get the pressure building and another to drop it by venting it as a gas. Of course we'd spend hours siphoning off the gas (which immediately turned back into a liquid) to freeze stuff (it was -150c or summit daft). Lots of shattered food, etc. but the favourite was to put some in an empty coke bottle and bury it at the bottom of a bin filled with 120 format film wrappers. After an unpredictable amount of time the bottle would explode.

Very childish but so much fun and kept us amused during the night shift.

Sorry can't help with the dry ice but the thread reminded me of "fun with cold stuff" ;)
