How do you do this: How do you use a rock tumbler to make faux sea glass out of the shards of glass?
While wearing thick work gloves, fill the barrel of the rock tumbler up about of the way with shards of broken glass. Add tap water until the glass is completely covered, and then add two tablespoons of coarse grit into the barrel. Seal the barrel, place it on the tumbler, and turn on the tumbler. Let the glass tumble for 7 days. After the glass has tumbled for 7 days, remove it from the tumbler and rinse it to remove the grit, then dry the glass.
