We took Lego blocks and stacked them about 6 blocks high. Wrap the mini Lego tower
in non-stick foil (non-stick on the inside of course). Take out the Lego blocks and pour in clear pony beads.
When you have enough, place them the foil covered pony beads onto a lined cookie sheet, baking at 425 for about 20 minutes, or until they are melted. *Note: make sure your windows are open when doing this!
After they've cooled, remove the foil. You'll have to use a belt sander to grind down the edges. My boyfriend used pliers to hold the cubes while he did this so he wouldn't grind his fingers too.
