How do you do an experiment showing how the moon creates tides?
Just had another thought. Along with the above, you could (if you don’t find this too silly) do a couple of demonstrations. You could take a piece of cloth completely soaked in water and demonstrate that if you suspend it and leave it untouched, the top of the cloth will dry before the bottom does. You start by assuming the gravitational attraction between the wet cloth and the earth, but you demonstrate that the water will act independently, and not stay stuck where it is on the cloth. Or maybe you could have fun setting up a centrifugal device that spins two equally weighted soaked cloths outward to demonstrate the same thing, and this would help you explain how there are high tides on the earth’s side opposite the moon, if you want to get into it that deeply. It will take some reading and thinking to figure this one out.
