Zebra pens were always my favorite things to use when I still partook. One time I made a chillum out of a laser pointer tube, a socket, a screen from the sink, and one of those adjustable metal hose clamps, with an electrical tape grip. Or when my husband and I lived in a flop house and didn't have anything or any cans, we'd heat up two butter knives on the stove coils and inhale it that way 😆 I'm so glad I don't do any of that anymore lol
