Every time he said Preasure, I thought of Billy Joel’s song “Preasure”. And I think the first time I heard that song was when my Geophysics teacher played it during our weather unit.

I remember being a really young kid with my grandmother in town. There was a street performer doing entertainment and some magic. One thing he did was lay on a bed of nails and have a big man from the audience stand on his chest. Everyone was so impressed. So little old me had to jump out there and ruin the show and explain to the crowd that the nails would never hurt him because there's so many of them and they are so close together so his weight is distributed. If he layed on 3 nails he'd be hurt. To my surprise the man was no angry, he was so impressed a kid saw the science behind his trick lll

Ok, so you're selling your videos as "Class". Then when you get all the underaged kids watch your videos, you suddenly plug a sponsor commercial? Bro, that's not done. Even though I really like that product, it's wrong. (and it's against ALnets and legal regulations. Content aimed at kids is not allowed to have commercials. (you should know, because you get asked this with every single upload and by uploading you sign off to understanding and knowing those rules.

Can you do an experiment or a simulation of a low pressure then it becomes a typhoon.. Iike to share it to my students for the subject environmental science and the topic is natural disaster.. And what happens when there is no plants or trees in the whole world. The question is what is the time taken to consume the oxygen and becomes carbon dioxide? Thank you sir

I would think nothing. When watching shows like Dirty Jobs, it seemed that the sewage systems, even for large cities, was just a little "stream", if you will, of sewage flowing down a massive pipe. My guess would be that, even if every toilet in New York was flushed at the same time, the different paths sewage takes to reach the sewer would mean the load is spread over a pretty large area, and so it wouldn't just suddenly be a gushing torrent of sewage. Additionally, I would imagine sewage systems have redundancies and overflow lines to keep the system from blowing up. I remember when the giant fatberg was removed from a London sewer. Obviously that sewer line was not the only line, or else the entire community around that blockage would have backed up and wreaked havoc. But they didn't. Water might take a bit to refill, particularly in very densely populated areas, but plumbing is "primed" already (that is, my toilet tank already contains water for the next flush).

Did the elephant clean its feet before walking on the floors? I would have added food coloring to the liquid stuff so it shows up better on camera. You did a great job on this.

When I was a kid we used to do a thing where the biggest guy in our group would lay flat on the floor & then we would position ourselves with 1 person at his head, 1 person at his feel & two people either side of him with 2 just below his shoulders & 2 people just below his butt. Then we would just use the pointer & middle fingers on both hands & lift him up off the ground. Pretty cool.

Also, you put the tape on top of the nail/balloon thing different for the 2 than for the 12. For the 2, you put the tape all the way near the edge. For the 12, you placed it further towards the hinges. That can change the outcome of your experiment, right?

Your question was “which would you let into your house” not “which would you not let into your house”, right? I think my understanding of your solution was lost in translation.
