Today we did a super easy experiment using glitter. The girls were excited to do anything that involved purple glitter. I will start with showing you a quick video of it. (I stopped filming too soon, so the last word that I say is “move”.)
- Bowl of water
- Dishwashing Liquid
What To Do:
- Add three pinches of glitter to the center of the bowl of water.
- Dip a toothpick into the dishwashing liquid, and touch it to the center of the water.
The glitter gathers in the middle all together. When you add the soap, the glitter moves away to the edge of the bowl. This is because the soap breaks the surface tension of the water.
What is surface tension?
the tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid, which tends to minimize surface area.
