For this experiment, you’ll need water, a dry erase marker, and a ceramic bowl or plate.
- You start by drawing a simple character on the surface of your bowl. A stickman is a good place to start.
- Slowly pour a small amount of water onto the drawing and watch as your stickman begins to lift up off the bottom. As this happens, it will start to move on the surface of the water on its own.
- You can then use a toothpick to swirl the water around and make your stickman move and dance!
This experiment works as a great way to show density because of the ink’s insolubility to water and its low density that allows it to float.
