I should have pointed out that it was YouTube. Paste it on the end of any YouTube URL.
Do a YouTube search on "windyz.wmv". That video debunks the MythBusters flag video.
Look at the dust kicked up by the astronauts' boots. It doesn't billow, as it would in atmosphere.
Do a YouTube search on "MoonFaker - Project Sandbox". There not being any billowing can be explained by the use of large-grained sand.
It gets kicked, travels in a ballistic arc, and without losing speed (as it would in atmosphere), falls back down to the surface
You're seeing what you want to see. Start watching at the 4:30 time mark of the above video. The sand he kicks up is traveling at an arc that's pretty indistinguishable from the sand kicked up in the Apollo footage. If the sand is not launched at a high speed like it is by the tires of a dune buggy and does not travel a great distance, large-grained sand will travel at an arc that's almost the same as it would be in a vacuum. The difference is very slight. Watch the Apollo rover footage and compare it to some dune buggy footage.
Here's an expert on video special effects who thinks the Apollo rover is a model with a doll on it.
