Not -quite- as risky as Russian physicist Anatoli Bugorski who put his head into a high-energy proton beam in 1978.

Title is a misnomer, at no point was his life at risk because the ball never had enough energy to reach him on the swing back... Which of course was the point of the demonstration.

If he'd given it a little push away, not just dropped it, (as he mentioned) it might have had enough energy left to bump him in the face. Probably not fatal though... exercise left for the student.

He really over-dramatised it, too.
