Mythbusters

Discovery Channel’s excellent Mythbusters dispute some of the moon landing conspiracy theories using a large vacuum chamber and demonstrate Galileo Galilei’s theory that, in the absence of air resistance, all objects fall at the same rate. The behaviour of a flag in a vacuum is interesting—intuitively you’d expect the lack of air to prevent movement (i.e. no wind, no flapping), but actually any small movement of the flag pole causes large and uninhibited movement of the flag itself. Cracking presentation of some basic science.
