#3 - Balloons
May/Jun 2006
Balloons are fun to play with and lovely to look at, but they’re also bursting with science. In Issue 3 of KNOW, we’re exploring the world of balloons. You’ll learn how balloons are made, what balloons have to do with predicting the weather, and how many balloons it would take to lift you off the ground. You’ll meet the four-legged passengers who first took a ride in a hot-air balloon and a scientist who plays with balloons for a job! There’s lots of loony balloony puzzles to try in our KNOW Fun section and we also tell you how to pierce a balloon without popping it and how to blow up a balloon without puffing. What’s more, if you’ve always wondered what the inside of your nose looks like or where to find the Big Dipper, this issue is for you. Up, up, and away!
