how to make gas or smoke come out of a volcano for a school project. ? Answered

I already have the vinegar and baking powder effect for the foaming.  No fire please since this is for a school project.

More baking powder or talcum powder, a tube coming up from underneath, blow gently into the tube to throw white powder into the air...?

If there wasn't the "no fire" constraint, I'd suggest an incense cone.

The classic approach for fog generation, of course, would be a chip of dry ice in a cup of water.
