Jar Jar Hour Glass Dice Tumbler

Works with a couple of an ordinary glass jars (I got these two from Ikea's jelly selection) that has four securing points along the edge of its 70mm glass lip (unlike the single helix of the original posting of this thing). It's the only thing called "Jar Jar" that makes any sense... amIrright?
