Question

I'm proposed a way I'd synthesize plastic...polyethylene to shape into a pipe

PROBLEM: not sure how or what I would use to make a mold or best method to produce a PIPE

not sure what a mold should look like to produce a hollow object like a pipe. OR what material I can use around the house to make a good mold.

I saw silicon but I don't think they have silicon in the shape of a pipe...


HELP!!

Thanks

note: I need to find a mold that can be used at home..not industrial scale

b/c presumably I'm a "poor college student" according to the HWK Q that asks us to create this pipe in the first place.
