It just so happened that next door was a TAP Plastics
store. In there I found something called a Tube-Pak
. It is a clear plastic tube with a red cap on either end. I chose one 18" long and 2" in diameter (cost: $3.50). Then I found some cool 1/4" colored acrylic rods
($3.45). I chose purple. Now it's time to build.
