Mr. Kyle absolutely loves science, so much that he decided to become a science teacher. He's been teaching for many years, and along the way he's come up with some fun lesson plans. One of his lessons included making a cloud in a very large water jug.

It's his 10th year making the cloud, and he's got it down. Every time he does one gimmick that fools the entire class. To make the cloud he fills the jug with a gallon of water, he starts a match and lets some of the smoke seep into the jug (the water needs something to cling to to make the cloud) and starts to pressurize it manually. He gets a pump and he starts pumping it. He pumps for about a minute and still no cloud. Everyone watching thinks that he is doing something wrong, but tinman knows why there isn't a cloud. What does tinman know?

This has a potential to be a great teaser- but misses since you don't explain why the release of pressuer causes the cloud to form.

If you can include this you have a winner...
