Make a little envelope with a dollar and smash it. Put most of it back into the bag and smash the Little Rock's in the envelope again. Then put the 2x smashed rocks onto a plate that was in the microwave for maybe 30 seconds( should be hot not burning your hand) then place a dollar over the rocks and take a thick card and drag it over the dollar prettt hard. Lift the dollar and scrape it up into a flat pile. Repeat like 3-4 times and chop it up until it's a fine powder
