Main Question or Discussion Point
If you have a string strung horizontally between two chairs, how can you get a balloon from one end of the string to the other, and then back again? You can use items such as tape, paperclips, straws, more balloons, ect. I have tried this and have found if you put the string through a straw, and then tape a blown up balloon to the straw, the ballon will travel to the other side of the string. The problem is how do you get the balloon back again?
