 All right, welcome back to Kids Spent Science. It's been a while. I've been working on a couple of different projects, but I'm back and I got an experiment today. So this is an experiment I do at my live science shows. It's called the Barking Dog. It's a glass five gallon glass alhambra bottle. And then you use 70% rubbing alcohol and a long lighter. So we're gonna fill the rubbing alcohol in the bottle and you only want just a tab off the bottom. So you don't need it that full. I've already poured it in there. And then I put a towel in here because you don't want any liquid around the neck of the bottle. And then we're gonna give it a swirl like so. And then we're gonna have the fun begin. So we're gonna try the lights out here and I'm just gonna light the top of the bottle for the fumes. And if it goes on just a little bit of flames right here, all you do is let it burn out by itself. There it goes. It's gone. That was a delayed reaction. Usually it doesn't take that long to go, but it kicked off and it burnt down the rubbing alcohol. So that was pretty cool. So to redo the trick, I'll do it again. We burnt all the oxygen on the inside, right? So the top will get warm if you do this multiple times. It's a little warm right now. So you have to be careful about that. The sides are cold, but we're gonna have to put more oxygen back in. So I'm gonna blow more oxygen and then we'll give it another swirl and try to get. I'm gonna give it off here. If it burns like that, you can either put it out or just lay it back. Good to be back. I'd love to hear those comments below.
