durkastani Valued Member United States 452 Posts	Posted 05/17/2017 1:01 pm Freezing could help. It's true, freezing contracts solids which means the coin contracts in on itself and the plastic contracts in on itself effectively increasing the ID of the tube while the OD of the coins decreased. Might have to leave it in there for a bit but probably your freezer isn't cold enough for the kind of shrinkage you're needing. See if there is a resource for liquid nitrogen and get them to fill a cooler for you. Drop your roll in there for 10 minutes and your coins will come out for sure. This technique is used on aircraft parts ALL THE TIME. Be very careful with liquid nitrogen, it will freezer burn your skin almost instantly. Wear insulated gloves when handling it.

Heat causes a material to expand toward ALL of its surfaces. Draw arrows toward all of the surfaces of both shapes. When you're done the circle has arrows going outward in all directions. The square also has arrows outward in all directions but it also has arrows pointing outward from itself into the area outside of its inner circular surface ;) Report this Post to the Staff

Then put it in front of a hairdryer on high,then right back to the freezer.Then the hair dryer. Do this a few times over the period of a few days and the plastic should become brittle enough to break with your fingers. Report this Post to the Staff
