"Hi, I'm tom Wright from Ginger Bread Glass and I'm here today to show you how to make a glass jar. Now were going to detach our jar from the tube. So I'm going to apply a punty, a cold steel punty here on the bottom. Close to the middle as I can and that will help us heat this up a little bit more. Little bit more juice here. Alright so were going to puff out the top just a little bit more. Going to get this a little hot again. So with that bottom piece you can kind of of just pull a little bit, help it and stretch it out a little bit. Alright now were going to blow a hole here in the tube. Alright, we detached it."
