That IS a nice one, but it would be more appropriate for undersea vents or pillow lava.

How about a super high-temperature furnace that actually melts rock, then pressurizes it to shoot out the top?

safety gloves!

and, if you do your calculations right, the resulting solution will have a pH of 7!

Supplies:

10 pound bag of flour.
Shop vac or leaf blower.
Window screen.
Bed sheet to hide your volcano from prying eyes prior to presentation.
Card table.
Stuff to stack under screen, on top of the table.

Carefully spread the flour on top of the screen. Position the leaf blower or shop vac under the table with the outlet aimed up at the screen.

When it's time for your presention: remove the sheet and turn on the blower.

Take pictures.

Then go on to discuss the eruption of Mt Vesuvius in 79 AD.

here is what i'd do - start with a cardboard cylender - maybe 4-8 inches in diamter - and build you're volcano around that using whatever you want. foam, cake, anything... -- i guuess really it all depends on how big you want to go.

my next thought it to use hook your air compressor up to a balloon... place the balloon in the base of the cylinder and fill the cylinder up 2/3 with your lava material... i liked the red cake batter idea.... maybe sprinkle you're volcano structure material over the lava to hide it...

then --- start pumping air into the balloon -- it will push the lava up and over the top of the cylinder and down the edges of the volcano -- and then once critical mass of the balloon is reached - BOOM -- lava goes everywhere and the top half of your valcano (depending on what you make it out of) could get blown off... You might even put some sharp pins or needles inside the cardboard tube to make sure you get the pop when you want it.

that's my initial thought...

heh... actually looks like it could be pretty cool -- def. needs more lava and more explosiveness!


is the volcano made out of dirt?

LOLOLOL... that was hilarious! I was in tears. Here's an idea: if you put some HCl in a 2L pop bottle with the most aluminum foil you can fit for greater surface area, put the lid on VERY quickly, this will produce -COPIOUS- amounts of hydrogen. The pressure will cause the bottle to expand to more than twice its size, and then explode due to pressure. However, if you put say, a lit candle next to the expanding bottle, you'll get a massive flaming ball of hydrogen. It's best to have the candle lit before mixing the foil and HCl. Oh yeah, don't forget to run for you life... at least 50 metres. That, along with the rest of the stuff, could make for an interesting volcano. It could be the initial explosion that blows off the top of the volcano.

Ok, i'm going to add a pin to make it explode earlier, much more lava, more smoke, and sulfuric acid with suger.... In about 1 day i'll post the results..... fun fun!
