i bought a plastic container at the grocery store. ( $5.00) a fish tank pump from walmart ($!0.00) a pool noodle from the dollar store ($3.00 go figure) i took my 1 1/2 hole saw, and drilled the holes in top of plastic, then i removed center bit from hole saw and in reverse cut plugs from the pool noodle and cut a slit in them like a pacman. i then painted the container flat black so no light could get in and then went back and painted white over it so it would reflect light. there you go. i have about $25.00 in it with paint included. PM me if you need more info.....
