Go around your garage/ loft/ shed with a stick. Hit things. Find the things that sound nice. Find the sounds you like, don't try and find the things that sound like pre-existing drums.

Buy 3 pairs of drumsticks once you've found your junk. Leave one pair normal; the second pair, wrap very very tightly with cotton wool and seal with glue or tape or some such. The third should be sanded, to be used for rubbing, although I do this to all drumsticks I use.

Vessels (bins, kegs, oil drums) can be filled with water to change the pitch. If you have things you don't mind trashing, you can make pseudo-steel drums by hammering dents into metal things. After a while you should have an idea about how to tune things and what you're looking for, which makes the whole thing a bit more musical.

If you want to go down the silly route, invest in cutting machinery and safety goggles.

If you want to get really silly, you can use a series of home-made devices to make aeolian drums and generative water pipes.

Try and think about the physics of sound when looking around - sometimes you have to hit, stroke or bow in a certain fashion to get sounds out.

Car junkyards are an ideal source of cheap, and often monolithic, percussion.
