Wanna see a trick? Sure. Here, blow up this balloon 1. Ok, now what? Now, I light this candle. Now what do you think will happen if I put the flame 2 under the balloon? It’ll pop, of course. The flame will heat the rubber to the point where it becomes weak and can’t hold up under the pressure 3 from the air inside. Right, except not always. What do you mean? Watch, first I'll put about a quarter cup of water in the balloon and blow it up. There, now hold this while I light another candle. This is the trick, right? You pop it and I get wet.
n.火焰，火舌，热情；v.焚烧，面红，激动
