Can this be used multiple times? With different fruits? Thanks!

Yes, I used lemon, grapefruit, tomatoes and potatoes!

What type of magnets are in the set? i.e. rare earth

Everything is in pieces. I thought it would be one large U magnet but it’s not. Also there’s a bunch of nuts and washers in the kit which is kind of messy. They just roll around everywhere

Is this a water based kaleidoscope, i.e. is the transparent container that you fill with beads also supposed to be filled with water?

Not is not water based. The platic container is a little loose so I don't think can hold any water.
