And when you combine the two and heat them up, something spectacular happens.

So we've got our zinc, which is our gray powdered metal here.

And then here's the sulfur.

Mix them together just by putting them into a glass beaker so you can see there.

Colors mix.

OK, so what's gonna happen is I'm just going to gently rotate the beaker so that the two mix like so No, that's mixed together.

We're going to go over to the fume hood.

Important, too.

Up oil middle go mixture of our zinc and sulphur and north to start the reaction we're going Thio need a source of heat on dhe instead of using a flame or anything like that were actually used a hot metal rod to get that reaction started.

Neil is going to be in charge of the blowtorch, and I'm gonna hold onto the road.

Okay, E trade happy customer.

Very happy.

I liketo actually bounced off my lab coat so it's a good job was wearing my safety gear.

Otherwise we would have been in trouble on this stuff that's left is zinc sulphide.

This is a very simple reaction.

Zinc and sofa you were using so far, that's the white powder that you're saying that.
