Dry ice only works great if the water it's submerged in is kept very hot. It's normally much to expensive to use dry ice for home haunters.
I use crock pots when I use dry ice. It works great. I put a small crock pot inside a pumpkin and put the dry ice in there too. It works great, but it is a lot of maintenance FYI.If you only need a small scale effect, say for something indoors, You can put water in a crock pot ( a slow cooking pot) set it on high which will keep the water warm enough so it will not freeze around the dry ice. If you put dry ice in a bucket of water alone, then the dry ice will freeze a layer of water around itself and stop until the pressure builds up on the ice and it pops open again, with some force I might add. Remember this is for a small effect like a chauldron or something simular, it will not fog the room up.

HellRazor, that effect you came up with from the pumkin is really great!
I have never heard of a grocery store giving anything away for free. What grocery store were you going to?You just have to find out when the closest shipment to Halloween is and go pick it up.
