Making a Plaster Volcano for Ammonium Dichromate Fiery Volcano Science Experiment

If you want to super charge your kids earth science science experiment with a more realistic Volcano depiction this is the first part of what you need to do, is make a plaster volcano kinda like what is shown in this here video here. A very quick snapshot video showing the rough outline of making a plaster Volcano to hold the ammonium dichromate pyrotechnic mixture for the fiery volcano science experiment. Although this would also handle the boring lame old vinegar and baking soda Volcanoes as well. Notice at the end that I made the opening a little bit more narrow, by adding plaster around the top edge to restrict the diameter, just think of the volcano as a more gentle rocket nozzle, the more you restrict the output diameter, the higher it will spew. This would only end up bad if you made some type of volcano pyrotechnic mixture that burnt too quickly, and it could not exit the vessel fast enough to keep the pressure down, in which case you would have a spontaneous unscheduled rapid disassembly. Also, we had to play with the proper mixture for the plaster. The instructions make a plaster that is far too runny. We ended up mixing it as quickly as we could, and then plop the whole thing onto the volcano, and then sculpt it. You don't have much time, a few minutes, so work quick. Don't forget to wear gloves when working with plaster, it really dries out your hands really bad. Also wear a dust mask when mixing it, you don't want plaster dust getting inhaled down into your lungs, and blocking your lungs intake of oxygen, or doing other nefarious things.
