We rarely had to wait in line for samples, but for some reason the Pucker Powder "candy art machine" always had lines standing at it. This is a 12 flavor bulk dispenser of sour and sweet powder. It was funny to watch people move around the dispenser, filling their plastic tubes with powder and making stripes of different candy configurations. You then tilt the tubes into your mouth, like Pixie Stix. The powder is loaded in plastic bottles that reminded me of toner for a printer. I really like the idea of an activity and a candy you can make yourself. Every flavor I tried was very good. I think you'll see this popping up in a store near you soon! It was very popular!
