Maybe if I worked for an educational channel. Otherwise, my HD $1000 camera with standard slow motion is good enough for me.
If you guys watch Time Warp on discover channel, they show this kind of stuff all the time. http://www.youtube.com/watch?v=w8Gxut0odyc
Time warp is a weird show concept, but fun enough for 10 minutes or so. I liked the cola-mentos thing in time warp.
