It would appear that this physics teacher’s hands-on demonstration didn’t go exactly as he planned it. I’m not sure what exactly he was trying to prove here – science was never my thing – but I feel confident in saying he probably wasn’t trying to take the butt-end of that axe straight to his beanbag.

To make matters even worse, it looks like the follow-up attempt didn’t really go all that smoothly either, judging from the blood stains on the teacher’s shirt as he gets up from the floor.

Maybe next time just stick to PowerPoints.
