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!

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!

As a physics teacher, I love these videos and would love to use them in my classes, but the auto-captions that they currently have do not meet ADA standards for my Deaf and Hard of Hearing students. ALnets makes it pretty easy to go through and edit the captions for grammar and accuracy (ie adding punctuation and correcting any words that did not transcribe properly). I know some of your videos have full and proper captions, would love to see that for this video as well!

i am going to go ahead and say astronauts weigh themselves by taking their weight and multiplying it by 6 b/c gravity is 1/6 the strength it is on the moon than on earth.

Something I'm not smart enough to grasp is that one time at my school we finished making something with plasticine and we went to the water fountains to get a drink and someone's hand got wet and the water didn't expand on the hand it just sat there and moved around leaving no residue on the hand and just sat there as a some sort of bubble it was cool.

I am late at the science class but, my hypothesis is that they punch a scale and see how much joule they put up. After that just divide them with the speed of your punch, and then they can say how much they weight. Btw before typing this i already watch the video but, before i watch it this is my first hypothesis

For the question how do astronauts weigh themselves I believe they yous straps that apply 14 lb of pressure on there body because then it's like Earth's gravity
