Как сделать отличную трубку из фольги (с наконечником под углом 45 градусов)

Exchange Supplies sell foil as a 'reverse transition intervention' to enable drug services to encourage people to move away from injecting routes of drug administration. This film was made some years ago to be used by drug services to show injecting drug users how to make foil pipes, in order to encourage them to try smoking. It was on a password protected area of our website, but we decided in 2012 to put it on our youtube channel as an educational resource as there was plenty of similar videos available, and our customers wanted to access it more easily. It is not an encouragement to anyone to try smoking drugs.
