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.
He really over-dramatised it, too.
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.
Physics works, and I'm still alive.
That does sound about accurate to life.
Alright now what happens if this happens in a vacuum?
The professor and all the students are killed.
The same thing, except the little bit of air resistance that stopped it slightly lower wouldn't be present.
And sends inappropriate messages to children who come to learn from him...

Unlike some, I don't name call and am willing to provide proofs for my claims...
Study the science behind the action and explain it and test it before putting your face in the line?
Thank you for my reminder to block at least 1 Lemmy idiot each day
I think I should implement this policy.
I'm actually not being sarcastic!
I've kind of learned after 20 plus years on various social medias... Honestly going back even before that, to the BBS days.
You just kind of realize after a point, not everybody's voice is equal, most people should just shut the fuck up and have no reason to ever be heard.
I honestly feel that no one should ever be shy to block someone if they don't like the bullshit, the tone, anything they say, the way they think...
Hell, block me if you don't like my loudmouth attitude!
Life gets easier on Lemmy when you block like a mother effer LOL
