pleasezzzzzzz helpppp

the rule is to built a cardboad boat with 1 roll of duct tape and paint

please don't bash me for posting this

cause i really need help

in highschool for class, i dont even know what it was called, but had to do with engineering, and the class had to build one. Well they had to fit like 5 ppl in the boat, so 1 roll of duct tape was impossible, but if it's for yourself i guess its possible. it was important to duct tape the edges, so water doesnt leak through, and to spray a crap load of water repealant stuff. i swear we wasted 2 bottles to coat the entire thing.
dont know if that helped at all, but im sure you can google it and find it.

lol well since it is about a form of transportation I'll let is stay if you want input from the car forum.

You might have a little more luck in the General Discussion Forum, but uh sorry i cant help you. Have fun figuring it out though.

When I was in high school there was a physics class that had a similar kind of project. I think the car forum would be a better forum to ask, there should be a higher concentration of technical people here.

First thing I would do is to research how boats are built, then try to apply similar methods of construction to what materials you have.

If I were to simply answer your question, it would be to start with a rigid structure, use panels, and seal the seams.

The structure will support the panels to prevent the boat from buckling when there is weight on it, then keep water out with the panels and seal the seams in the panels. Since your panels are going to be cardboard, you'd also want to water proof them.

also id say try to make it like spread out alot so as to get all the use of surface tension as possible

Ooh, Someone went to Yale!


Anyways, I'd use the paint liberally on the bottom of the cardboard to prevent the cardboard from getting soaked. and i guess the sides too.

I think if you also make the bottom of the boat thick, you will also keep the hull from collapsing in so easily.

Surface tension is actually not how most boats stay floating, it's buoyancy. If surface tension was the case, boats would be sitting on top of the water.

haha thats rite xP
but u could have some stuff floating to help u stay bouyant

dont you need to displace as much water as possible so it can hold your weight?

so.... lets imagine if you laid down on your boat, you'd ideally want a rectangular shape, but to make it float by displacing water and not just sit ontop, you need a ovular shape where the edges meet. So try to make a canoe shape but wider base so you can laydown comfortably in it for even weight distribution. seal the edges, apply paint on the outside where the water will touch the cardboard and on the insides to keep water from soaking in. I would try to use all of the ductape to seal my boat. GL tell me if this works. This sounds like so much fun!
