SCIENCE CLASS #4- How to Waterproof Your Hand

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- slthrow.info/solution/nMLEjLuokt2x3tg/video.html

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!

    Mark, your videos are fantastic thank you. You did leave out an important factor with water going up the trees: transpiration. The evaporation of the water out the pores of the leaves creates a pull like sucking on a straw and pulling the water out of the tree. Cohesion and adhesion assist in this, but will not alone cause the water to climb high enough, it’s the pull from the top, the tension at the top working with the two forces That causes the upward movement of water. You probably already know this but I thought it was important point to share. Thanks again for your inspiring work.

    For what it's worth: I think you'd be a great high school science teacher but I think your skills, personality and passion would be of a greater value outside of the constraints of our standard education systems. Please continue to educate hundreds of thousands of children AND adults by making videos online or via a similar medium. Spend your time there instead of in a standard classroom.

    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
