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- https://youtu.be/8aaXZDazPxs 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.
