Investigating resistance

Still with the Olympics in mind, the Junior Science Club investigated how the lack of resistance made objects move faster or further with less effort.  This concept is particularly important to high performance athletes who wear special clothing to reduce drag to an absolute minimum to enhance their performance.

It was interesting to see if a cardboard tube could direct the flow of
air more efficiently and make the balloon go even higher
