Push Me a Grape

In this physics activity, learners experiment with the attractive and repulsive power of magnets. They move a grape using a Neodymium Magnet, and explore how the strong magnet repels the water in the grape using diamagnetic repulsion. This is truly a "Wow" moment for students, as the results are not what most people would expect.
