If you have a flash that you can point up you can bounce it just attach a anything that is made of stiff white paper to your flash with a rubber band like an envelope, business card, 3x5 card, back of an old photo, you get the idea. Suddenly you have a whole lot of things you can bounce a flash off of, provided you have a rubber band or something to attach the bounce card to your flash.

Digital, it doesn't have the same tonal range as film, but you can use it for test shots to see what film you want to use. I believe that digital photography is the fastest way to learn that basics of how to perform a given film technique, it won't show you everything, but it can be a great learning tool as long as you shoot, look adjust and remember, spray and pray is not the way to learn.
