Chem 101 (I got an owie)
Posted by Anonymous on Thursday, July 10, 2003 4:27 AM
Here's one for you chemistry dudes out there.

I was wiping up a large ('bout the size of a dime) dollop of Zap-A-Gap with a clean tissue. I also had some Model Master Metalizer, Aluminum Plate, on my fingertip.

When the three got together the temperature went to "Very, Very Hot!" in less than a second. So fast in fact that I threw the tissue across the room and shoved my finger into a bowl of water to cool things off. It took the skin off and it may leave a scar.

Is there something about Zap-A-Gap and MMM Aluminum I don't know? I've been using both for years and never saw a reaction like that before. Did the tissue somehow have something to do with it?

Could be that the MMM (contianing some flakes of aluminum) reacted with the solvents of the CA. I'm not sure of the exact compositon of the solvents of these two items, but I doubt that they reacted with each other. it had to be the metal reacting with the CA. It sounds like the kind of pyrogallic mixture that powers the space shuttle (also uses powdered Al). This type of mixture is extremely exothermic. the tissue had nothing to do with it other than to become fuel and a mixing vessel. Bruce D. Pease (retired Chem teacher)

I sorta figured it was something along those line. I know that aluminum powder can be pretty volatile in certain situations. And I was kinda kidding about the tissue but it might have helped by letting lots of air into the mix.

I'll be a little more careful when I mix MMM and glue in the future. I can just imagine watching a model melt down before my eyes.

That's word for word the exact same statement made by one of the Hindenburg survivors.

OUCH thats gotta hurt. Thanks for the heads up on that painful combo. What about starting a "most painful whoops" thread? .I bet it would cause quite a few laughes plus isn't it better to learn by someone else's mistake? ......Greg

An interesting sidelight to this thread...Buddy Ebsen, the actor best known as Jed Clampitt (Beverly Hillbillies) was the original Tin Man in the movie Wizard of Oz, but after 10 days into filming had to be replaced. He had developed a severe allergic reaction to the Tin Man makeup, which, I believe, was made of ground aluminum powder paste (I guess sort of Rub n' Buff of the thirties). Curiously enough his replacement used a different kind of maakeup.

Perhaps the tissue was the root of your problem.
I glued a piece of tissue to my finger with ca recently and it got real hot and I was wiping up a spot much smaller than a dime.
I had no paint on my fingers at the time.
When I have put ca on balsa it heats up as well,even smokes.
I hope ya' heal well.

Try having your bonnet support stand come down and lay on the posetive battery terminal... Didn't hurt physically, but the smoking, crackling bonnet hooks and holed battery sure as heck kicked my wallet in a tender location..

I almost wiped out my garden fence when the thing slipped into neutral on the transfer box (i.e. stop playing with it you fool!) and rolled backwards. The landlord would not have been happy.

you can find out more about chemicals from a HAZ - 11 class, I had to sit through one for the army, it's very informative and helpfull!!!!
