I have a question Mark Rober: Ok, so if I 1v1 someone and I beat them 30-0 how much better am I then them, cause im not like 30 times, or infinitely times better because that would still be zero. Am I just “better” or is there an explanation to it?

Just want to say that I witnessed the bed of nails experiment as a child in a museum and as soon as you explained the science of pressure and force that experiment popped into my head. Didn't even realize you had the same experiment set up. Very cool. Thanks for these!!

But please if there is any space (or basement) UNDER the floor, do NOT let an elephant walk on it. Take the 110 pound lady (or Joe Exotic) and politely ask them to remove their heels.

Wait, so "elephant" was the RIGHT answer? LOL! Great explanations, keeping it simple. Reminds me of a legendary story in the 1970s that some engineers synchronized the flushing of toilets in a multiple-story dorm at Rutgers College. Since we didn't have Internet back then, I'm not sure if it actually happened, or what the results were. Thanks, Mark!

Elephant was right , jumping outta parachute is absurd , head of water gives u a pressure of water at a height , the 6 ft head means 6 feet of water above you< 60 ft hd , more like hospital visit ?

As a physics teacher, I love these videos and would love to use them in my classes, but the auto-captions that they currently have do not meet ADA standards for my Deaf and Hard of Hearing students. ALnets makes it pretty easy to go through and edit the captions for grammar and accuracy (ie adding punctuation and correcting any words that did not transcribe properly). I know some of your videos have full and proper captions, would love to see that for this video as well!

At a science museum in Baltimore there is a massive bed of nails. My school took a trip there and we all laid on it. I had no idea why it did not hurt cause we talked while they explained it but now i do. (this was minus the nails on top and the cinder block and sledge hammer)
