Amateur Scientist & MechE grad using this platform as a creative outlet through entertaining, educational, and sometimes comedic STEM videos. I love experimenting with new topics and video concepts, so don't be surprised by the occasional outside-of-niche post. Thanks for watching!
My guessed before hearing the answers Round 1: The copper wire would need to have been enameled to prevent shorting. You specified it was bare. A clever trick question but can’t fool everyone. Round 2: The polarizer one is fake. The middle filter is one that rotates the polarization; like a sugar solution or liquid crystals. It’s not a polarizer as you said it is. I was wrong. Well, we come here to learn, don’t we? Round 3: A is fake. The straw will roll in the direction of the greater surface tension, where the bubble is intact. The stated prediction is opposite to what will really happen.
This is the first time I've gotten two wrong, but I'm pleased that I've learned something. Though failing to spot that the copper wire wasn't insulated is definitely on me
Prefect score, though I was pretty torn on Round 3 between all wrong and bubble wrong, but I ultimately went with bubble wrong as a 50/50 guess; either way, I was certain that the bubble thing was false, so I'm taking that as a W.
I got trolled by the bare copper, didn't notice that detail. Figured it was weird that there was no "all are correct" options on this video LOL Steel wool wasn't too difficult and I thought of surface tension for the straw, yipee 🥳
