The blade of a standard 10" table saw rotates at very close to 100mph (150 fps). Of course, the teeth of the blade point such that they will maximally engage the wood if it gets loose. So anything of small-to-moderate size will accelerate to as much as 100mph. Using 150 fps, it will depart the 2-foot table of the saw in about 15 milliseconds, so (like the author of the video, and me, once) you will only understand what happened after it's over. The usual reaction is to stare dumbly at your hands, and then stock up on push sticks, push pads, and work holding jigs ;-).
