Redox Reaction: Holiday ChemisTree! Copper + Silver Nitrate (Holiday Chemistry)

I swear that it it total serendipity that I'm posting this on Christmas.

I schedule posts way in advance (10/1/23 is when I'm posting this one) and don't pay any attention as to when they get posted. I just line things up so they're on the next available Monday. 

We couldn't get any better a time to see the redox reaction between a silver nitrate solution and a copper Chemistree, could we?

Rainbow Fire Halloween Jack-O-Lantern


You know where you shouldn't get your science advice? Pintrest...and Facebook...and I'll add in Tumblr, too.

Yes, a pumpkin flaming with green fire would be pretty stunningly cool. The thing would terrify every little kid passing by...which is the goal of every Halloween, of course.

But the pumpkin would require the use of methanol.

Methanol is, as I have said a number of times before, bad...dangerous...deadly...

No good can come from attempting this demonstration, folks. I'm especially worried about the notes at 1:50 that says 'The colored flames last several minutes. If you want to keep it going, you'll need to add more alcohol.' DON'T DO THAT. Even if the flames look like they're out... Even if the pumpkin is still hot, it can catch the methanol fumes on fire as you go to refill your flaming, autumnal ball of death.

You might not die, but you might wish you had.
