Amaze classes with the fact that pruny fingers after a bath are actually the result of osmosis—thanks to the water from the tub. Using an egg, vinegar, and corn syrup, the video teaches about osmosis using an interesting demonstration. The narrator then explains cellularly and chemically what happens between the egg, vinegar, and corn syrup over a few days' time.
- Incorporate the video and experiment into a unit on osmosis and diffusion; perform the experiment as a demonstration or allow groups to complete
- Have classes perform this same experiment but play with the solutions; for example, add different liquids to the mixture of egg and vinegar to see how much water will move into the egg through osmosis
- Video is most appropriate for middle and high schoolers
- Video is short, less than four minutes, and is easy to incorporate into lessons
- Engaging experiment is fun and attention grabbing
