I need to know a design for a cardboat boat that will hold a person and float across a pool.?
It’s for a physics class.
it requires you to be able to seal the cardboard, so it doesn’t absorb too much water, after that its a fairly simple plan, using a design like a canoe, kayak or dinghy, create a displacement area big enough to support the weight of a person, it should be around the same size as a normal boat, as the displacement pricipal won’t change too much with the material. The hardest part will be stopping it from absorbing too much water, but as long as you can keep structrural integrity, it should get you there, I’ll leave the water proofing up to you, it is your project after all.

You will need lots of foam. And a sealant. Carboard gets soggy when wet, dear. Those culligan water bottles, emptied, make good flotation devices. You can use those if your design to elevate your cardboard so it doesn’t get wet.

its not possible, carboard will float but not with weight on top of it and cardboard becomes waterlogged very fast. the only way for you to make it a cross on cardboard is placing like a pool toy on the bottom of a carboard box
