Fifty feet hung from a line over the shower should make seven or eight loops going down to the bottom. The film should not touch the bottom nor itself. It will dry in twenty minutes. You may want to absorb the drops that collect at the bottoms of the loops with a little paper towel. It is just as simple to develop black and white 16mm, though only 50 feet at once is manageable unless you get a huge wine jug or something.
Color is easy too.
You can also make all these solutions from scratch. With Super-8 negative, you can refilm off the screen using filters in 16mm ektachrome, to make a 16mm color negative without the orange mask. With an optical printer you can also make 16mm positive prints with 7386 stock, available from Kodak and developable in C-41. The beauty is that your original stock stays pristine while you edit a workprint. Good luck, and don't hesitate to bombard me with questions.
