Hey, got a quick one for all you who have done this. I am trying to make myself some of these pipes, but I can't seem to get the bubble blown right. I am using 1/2" tubing with 1/8" wall. Every time I try to blow a bubble, it blows out, and for some reason, I cant get it to be a long bubble. I am thinking either I am getting the tube too hot, or I am using tubing with a wall that is too thin.
