Maybe I am just smarter than the average bear, but this rainbow- making device could net quite the profit. You place the device in a window with sun shining in and a rotating Swarovski crystal will split the light into the rainbow spectrum. Then simply find the end of the rainbow and the pot of gold will be yours. Hopefully the gold is worth more than $38 so you can profit, but if not, no biggie.
