He uses a home-made (??) one-millionth second flash gun. An ordinary one is too slow, he says it's about 1/1000th second. (I thought they were rather faster than that, like 1/10.000th sec, depending on exposure.)

Objects and bullets
Photographing bullets passing through things has been done before, but Alan Sailer is good.

At low power settings common speedlights will indeed give you flash durations in the 1/10000..1/40000 sec range - but that's still 25x to 100x as long as 1 µs ...
For very fast moving subjects that's about the same difference as if you tried to shoot sports wit 1/10 sec instead of 1/250..1/1000 sec ;-)
