Hang this holographic prism in the window for delicate, changing color effects. As the sun shines through, it throws splashes of red, yellow, green, blue, violet and more around the room. The glass disc is 4-1/8" dia x 1/4" thick with a chrome-look frame. Comes with a suction cup hanger to mount it on a window. (Find a way to make it rotate for an especially cool effect!)

So that your wheat can see where it's growing. OK, they're really for all those teeny-light needs: dollhouses, models, robots, train sets, like that. This set was made to be a repair kit for Aura Grain of Wheat rope lights, and you can still use it for that, but you'll get an 18" length of 3/8" dia clear or colored rope with (18) white lights inside, plus (2) 1-3/4" pieces of clear shrink-wrap tube, and (2) 2-pin splice connectors. The 18" length operates at 120VAC & draws approx. 9 watts. Use it as is or slice the tube and remove the 6 volt GOW lights.
