I needed a float to suspend a net in the pond (I was netting baby koi
and keeping them separate from the big guys and the frog). Using some
1/2 inch clear flexible plastic tubing, I cut an 18 inch length then
joined it with a short piece of hard plastic air line. Both the tubing
and air line I bought by the inch at a local aquarium / fish store; it's
also available at Petsmart, etc.

I think i have air line! The hobby shop had zilch.
