How can i make a sailboat by hand ? - toy sailboat parts characterize

Although it is a project for my science classes. We can not be used pieces of toys or things that have happened is. since we are dealing with things that we find in our house is not such a thing as water bottles, straws, etc.. we have to do it by hand. I have no idea how. I need ideas how I can do for yourself to float. If you give me a hand with which I would be very grateful for all my life. must be something simple, but something that would work.

Thank you.
