How to Make Rings

1.5" x 27" PVC pipe (2)
1.5" PVC end caps (4)
Playground sand
1" x 72" webbing (2)
one gallon paint bucket
oven mitts

Steps:
1.  Preheat oven to 400 degrees.
2.  Fill the two pipes with sand and firmly cap both ends.  The pipes must be packed with sand as tightly as possible.
3.  Cook the pipes for ~10 mins or until soft.  Remove one pipe and promptly wrap it around the bucket until the plastic cools.  About 60 secs.  Repeat for other pipe.
4.  Remove the end caps and remove the sand.  Run webbing through each pipe in both directions.  Pull the it tight.  Tie off the ends with a double fisherman's knot, making loop for a biner.
