  1. This is the same sort of near-instant pressure crushing that happens when a submarine’s hull is fatally breached.

    Just, that quick. One second, fine, the next second, a crushed can.

  2. I did this same experiment as a kid…with a soda can and an open flame. Heat up water in it, then turn it over upside down into a water bath and the can collapse on itself from the vacuum that is created.

  3. I use to do this sort of thing with soda bottles in school. Fill them with hot water, dump the water, cap, throw them in my mini fridge and scare my roommate a few minutes later with the crunch. It was moderately amusing.

  4. A bunch of teenagers, dressed relatively modestly, standing outside what looks like a church, doing science experiments, while mom reminds them of one of the Fruits of the Spirit. This has to be a homeschool coop.

  5. The lady in the background saying patience like some sort of Disney character was the most annoying thing I’ve heard so far this week.

  6. I know the internet has made me impatient because I got to 2 mins and kept thinking “they should’ve cropped this shit”

  7. I can only imagine the disappointment of the instructor when the girl says that she’s scared it’s going to explode.

  8. This is why teens die like flies if you leave them to their own devices. If something didn’t happen in two seconds and they can’t see anything happening, that means nothing is happening or ever going to happen let’s touch it NOWW giggle giggle

  9. You can tell that chick put a lot of time into this presentation and had the guts to do it in front of her classmates so I am really glad it worked in the end.
