Woowee! I blinked and all the sudden I've uploaded 12 new YouTube videos describing the science behind basic STEM demos you can do at home 🏃🏻‍♀️ YouTube.com/SpaceGal⁣
⁣
This one in particular was fun. The floating stickwoman works for 3 reasons:⁣
⁣
1) due to the oily silicone polymers used in them, dry erase marker ink is less sticky than regular ink, so it is easily unstuck from the plate with water⁣
⁣
2) it doesn't dissolves in water. So when it is unstuck, that ink sticks together as that thing you drew - our stickwoman⁣
⁣
3) dry erase marker ink is less dense than water, so that buoyancy force pushes it to the top of the water in the plate.⁣
