Our project is to make a cartesian diver modelThe example our teacher has given us is a water bottle filled with water with an eyedropper placed insideWhen the bottle is squeezed, the eyedropper goes downWhen you release, the eyedropper goes back upSimple, right? Our task is to make a cartesian diver model using any household item except an eyedropper and any form of a ketchup packetIf you can help me, that would be awesome! Please list items needed! Thanks!
Yeah that's great, go for it!!!
those are pretty safe.b/c the hair is held together.
Anything that is 1) small enough to fit into the water bottle (or other closable, squeezable bottle - like a 2-liter soda bottle), 2) normally heavier than water, and 3) can trap an air bubble of sufficient size to make it float should workSome ideas: a piece of aluminum foil shaped to capture an air bubble a cap for a pen (if it normally sinks, or you could add weight to it) Hope this helps
