ive found a new way to get a good ammount of resin from your pipe
1.fill pipe with hot water
2.shake as hard as you can while covering up all holes for as long as you see fit
3.get a small plastic bag and cut a very small bit off the end so only a drop can get out
4.pour the water from your pipe into the bag and squeeze till all the water is gone
5.enjoy the nice bag of resin you have
i just did it and it worked great
