How to make Gymnastics/Fitness Rings from PVC Conduit

Step 3 Fill pipes with sand and cap

Tape one end of a pipe and fill it with sand. Tap the pipe on the ground to compact the sand. I used Gorilla tape which seemed to hold well and when it was later removed, it didn't leave a sticky residue behind. When you are done filling the pipe with sand, tape the other end. Repeat with the other pipe.
