Great, in my test tube, I'm going to first melt the potassium chloride. So I'm going to go ahead and do that. I'm going to pull the sash down, ahead and start melting this. And after it's melted, or after it's melted, then we're going to add the gummy bear. And with this higher temperature, it will actually give the reacting molecules enough energy to get over the activation energy barrier. So remember, for every reaction, we do have an activation energy. So even though the reaction is directed to be spontaneous, the reacting molecules still have to have enough energy to form a transition state. So we're almost there. So if you ask what come in, you can see this. I'm going to turn the light out. Good. Hopefully there's no point in seeing it. Okay. It's starting. Yeah. So hopefully you see why we do this in the head. So hopefully you see why we do this in the head. Did anyone catch the collar, the light, kind of purple, when he had the as well, that was purple. Well, but not actually wasn't the gummy bear. It was the potassium. Okay, the potassium chloride. So I remember the potassium in a flame gives it kind of a lavender collard flame. Well, that's what you were saying here. All right. Any questions?
