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!

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

The paper clips didn't sink a bit bc of Archimedes and displacement.

The only science class I will ever attend (hopefully). Mark is actually interesting, explains things in an easy to understand format, and his voice isn't boring or flat. Other science classes explain things it a format I will never understand, their voice is so boring and flat I want to fall asleep, and don't use examples and diagrams. My real-life science class does use models and an easy to understand format, but their voices make me wanna fall asleep and the concepts they want to teach me are impossible to get a grip on without being explained properly. This is one of two science/engineering channels I will willingly watch, keep making great vids and thanks for teaching me! :D

Fun video! You say at the end that water is magnetic. Is that really true? I know it's polarized due to its 4-point pyramid shape with 2 hydrogen atoms and two electron orbitals around the oxygen atom, so the side with the two hydrogen atoms is more electrically positive. I'm guessing that running water acts magnetically due to the moving charges but that still water is not magnetic. To test this, I think I can use a plastic sheet with a magnet behind it to watch the behavior of water droplets at various speeds, and I'm hypothesizing that still water won't be attracted to the magnet!
