Lots of juicy demos relating to surface tension! NO CLASS THIS WEDS!! I'm filming one of my normal monthly videos that day. Back on Friday though!!
Go check out Dianna's awesome channel-
CHALLENGE- float as many paper clips as you can and then come up with a creative way to ruin the surface tension and have them all sink. Tag me on any social media with your responses.
Question for next time- How do astronauts weigh themselves when they are floating and weightless.

Thanks for attending! Remember, no class on Weds because I'm filming a normal vid but we'll be back on Friday with a super juicy one!

I don't get why people gave this a 'thumps down': if you don't want to know how to water proof your hand, JUST DON'T CLICK ON THE VIDEO

I have a question. Does cohesion and adhesion occur in substances other than water?

Absolutely love this, would totally have liked science if you were my teacher when I was in high school or even college! Would love to see better lighting though, it’s so dark compared to your regular videos. Congrats on all your success, your truly an inspiration to learn and grow, and of corse to catch sticky fingered morons who steal packages!

they might use ropes to create the exact pull like the one that earths gravity puts to weigh themselves in space

Question: i broke several bones in my hand and had reconstructive surgery, there was massive swelling. When i started PT i noticed that the skin on my hand was ultra water proof like teflon. Its been this way for months now. Do you know why??

My uncle used to put soap in the water tank where the cows drank to keep the ducks out of the tank. It broke the surface tension. The ducks would sink so they stayed out. I guess it was better for the cows to drink a little soap than duck crap. We also put soap on the hill in our front lawn. We had a lot of clay in the soil. The water would run off. The soap broke the surface tension and allowed the water to soak in.

I just want to say that the way you teach is in my opinion the best way to go about it. For me at least, I learn and memories subjects the best when I get a mental model, only then do I feel like I fully understand it, which is exactly what you do. So if this is how you want to teach at schools, your students are going to love you. You'll be THE mister Rober from school, not just that famous guy from the internet (at least, that's how it worked at my school, the best teachers get school-wide recognition). Good luck!

I like your videos but this time it is too chaotic. You clearly didn’t have idea how to explain all of this information and you tried to improvise it a bit. It failed but don’t stop. I believe you will make progress as a “teacher” and your future videos will be much smoother

Soap breaks down fat.. Yet fat is used to make soap.. Talk about washing the hand that feeds you.
