Volcano advice...

Being Military, I can't conceive of having an underperforming volcano and this year, my daughter (or son... i forget now) has to make a volcano. I need you rhelp. I know there is at least 1 chemist here and at least 34 people smarter than me.

My order of preference is this:

1 - Mountain that BLOWS it's top via remote control (chemical reaction caused by electricity or chemical release) and spits red crap and oozes it for a good 5-20 minutes

2 - volcano that I use something wired to cause some effect similar to the above (I figuer this is a wash because I can do remote detonators)

4 - a volcano I poura chemical into to cause a oozing reaction

5 - #4 but i light a july 4 sparkler and sing the italian national anthem.


Your help is GREATLY appreciated.


EDIT - Apparently the chemicals need to not blind, kill or maime the kids and wash off, non-toxic. pbbbffft

Thermite. If you have a lot of room, safety equipment, and paramedics on standby.

2500C

I'm going away for the weekend, but I'll do some research when I get back.

My potassium permanganate/glycerol volcano is quite impressive, but the permanganate is something you can't get. *I'd* have to steal it, if I wanted it.

So that's out.

My kids made their volcanos using vinegar and baking soda
with a little red food coloring. This is is an acid/base
nuetralization reaction. Very dependable, but also old fashioned,
if you ask me.

For today's kids, I would recommend Mentos and Coke. This
appears to be a complex interaction of surface tension in the
coke breaking down while simultaneously nucleation sites on
the Mentos are activated.

Don't forget to add toy soldiers to represent the doomed villagers.

Update: Don't ever drink Coke and eat a Mentos at the same
time. According to authoritative sources (i.e. the Internet),
it will make your head explode.

I guess sticking dynamite under a heap of sand wouldn't quite cut it. Plus, the stuff is probably pricey...

did the mentos thing this weekend with a diet coke and 3/4 pack of mentos. blah blah blah, wasn't worth the effort. So make sure if you use this you use the full formulae!

We had a project like that in chemistry, one person bought a bunch of 2-litres of sprite, and a ton of mentos. The key thing is this: put 1 entire pack of mentos into a full 2-litre bottle of sprite, and BOOM! HUGE EXPLOSION!!

That was on Mythbusters, but they used diet coke and mentos. Freaking awesome. They got the darn reaction to shoot up over a building, but I forget how high it actually got. Pretty insane stuff. :D

i coulda sworn it was regular coke...and i cant remember how high either, but i know it was at least 30-something feet.... even had to extend their measurements since they went so much higher than the building. lol

saw a video of a guy on google or youtube that ate a pack and drank a bunch of coke.... he was all cool and proud in the beginning... at the end of the video he had shit himself, could barely stand or talk and was very humble

Ouch.


Serp...I dunno. I swear it was diet! But I might not be remembering it properly. I thought they did some investigating, thinking it was a reaction from the fake sweetner or somesuch. But now..I have no idea.

very much like a volcano though. :D

Ya, I think the thermite is out... I hear they regulate it to the inegar stuff... so perhaps a PC type Fan hooked up to a car battery with a remote on... to blow it up in the air... and a sparkler
