You've got 5 hours - forget about doing any plastic vacuum forming!

The most accessible option would be to make a giant *paper* cup. Get some of those waxed paper cups, undo the seams and unroll. Get as large a piece of paper or cardstock as you can get your hands on at the local arts supply store. Scale up, cut out, and glue together.

If you need it to be waterproof, you could try waxing the paper/cardstock yourself, using a hot iron and/or hair dryer. Practice on a smaller model first...

expose a cup to radiation and it'll grow, lol more seriously though I don't think a vaccuum former would work, it would stretch the plastic too much. As seen on How it's made: Plastic bottles are made by making a test tube shape wad of plastic, insert it in a mold cavity and they blow hot air into the wod of plastic, making it take the form of the mold, then the mold opens like a clamshell.

Well, in order to make a plastic version, which is what it looks like, you would need a mold, and fill it with plastic. I don't know any other method besides casting one in plastic.

Rephase: Ask your relative where they got the pic, and talk to the people that make them, they might give some info.

I would also except a website to buy them, but I would prefer building. It's more fun and cheaper.
