[spotlightman1234]

you can just use a ketchup packet if you want to do this at home

You can make one at home with a 2L soda bottle (for best effects) and a pen cap + clay ball attached at the clip, or with a knotted straw and paper clip at the bottom :)

Squeeze the bottle to see it sink, and let go to see it float back up
