（单词翻译）

Wanna see a trick? Sure. Here, blow up this balloon1. Ok, now what? Now, I light this candle. Now what do you think will happen if I put the flame2 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 pressure3 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.
