Anyone know where to get a 2 - 3" metal sphere for cheap to use as a top load? Aluminum foil isn't cutting it.

Ikea rimless salad bowls. They range in size from 2" diameter or so to 12". Tape them together with foil tape.

There are always toilet floats also.
I also have plastic toroids which are great. Just need to be covered with aluminum tape. They are about 6" dia x 3-4" height.

If you pay for shipping, i'll mail you out some for free.

Why not use aluminum ducting to make toroids?
