hello,
In the past, I have seen people use dry ice for fog effects on stage. I have seen massive amounts of fog produced, so much so that a large room was covered in fog, up to about 4 feet off the ground. I've read that large amounts of fog can be produced. However, yesterday I placed a 20 pound block of ice in a bucket of hot water, and the effect was disappointing. The fog flowed over the bucket, and disapated within a radius of roughly 3 or 4 feet from the pail. Any ideas why it didn't work, or how I can fix it?
Several sites warn you not to use too much fog, since you can fog up the whole front of the audience. I am looking for an effect similar to this in magnitude...any help is appreciated :-).

Your mistake was in using warm water. This creates more fog, but the fog disappates very quickly. Try using cool water: it won't create as much fog, but the fog will last much longer and spread out farther.

You can generate more "fog" by breaking the block of dry ice into smaller pieces, and by using a container with greater surface area than a common bucket.

I think that warnings for carbon dioxide from dry ice. It can suffocate people. I'd crush up dry ice so I can control how much I can add. Don't use hot water. Cold water should work fine. I wouldn't use just big chunk like that though.

You need a fog machine!
The Oriental Trading Company (can be found online) has one for under $100.; I've ordered one, myself, for Halloween!

Just use cold water next time, and not too much. And a fan will also help. Your problem was you used hot water. And just put a chunk on a plate, not in a bucket.
Don't worry, it won't hurt anyone. It dissapates into the air too quickly. (Unless you TOTALLY overdue it).

the effect you're talking about is from a chemical fogger, one used for concerts and such. you may be able to find one at spenser gifts, or try a local music store. they may even sell the replacement fog juice. good luck!

Call your Fire Department....
We had a Fog machine we used for practice fires... Maybe they have one you can use if it is for a public event like school..
