Help using dry ice?

Question

I'm going to be filming a video for a project in class, and my partners and I need a fog effect for the video. We're trying to keep it low budget so a fog machine is out of the question. We'll be filming really soon, so does anyone know if I can just store it in a cooler at room temperature? Also, we're buying about 2 pounds worth. Anyone know how to make the most of it?

PS The video is about 2 minutes long, but we're buying a little extra in case we have to do multiple takes

Answer 1

DO not use it in an enclosed environment, like a shut up class room, that much CO2 cna cause problems with gettting enough oxygen,

that said, buy cubes or pellets, spread them in the WIDE container in a shallow layer and pour on room temp water, its a very wispy fog, PS you can get el cheepo fog machines now at drug stores and the like after halloween, they will run in burst mode only ( lots of fog for a few seconds at a time) to keep it low to the ground set a tray of ice in front of the fog machine to cool the vapor

Answer 2

Standard small styrofoam cooler is best for keeping it. Film with a black cloth backgroung to see the "fog' from the dry ice. Watch out, the stuff will stick to your skin and give you frostbite. Handle with gloves.

Answer 3

Be careful as dry ice is CO2 and if it is in a tight room can kill if u are laying on the floor. CO2 is heavy enough to smother fire.

Answer 4

yes...store it in a cooler...if u want to make it last longer...have it chopped into smaller pieces
