Pretty much anything light that won't fly out the barrel will work to mix the fuel. Pennies were plentiful and available. I just can't use them shooting straight up.

My hose clamps aren't very tight.

If you want tighter hose clamps, just use steel 1" steel socket weld couplings, (McMaster), and cut slivers off the ends like here.
