I am needing to make a massive cake with a volcano as a centerpiece. I'd love to actually have the volcano smoking out of the top of it, but I'm not sure what I should use. Any suggestions?
You can make a well through the top of the cake and put a juice glass or small can deep into it (the can can be tomato paste size) in the hole. Put in a bit of dry ice and a bit of water and it should smoke.
