I didn't know there is super clear variety, interesting. I once tried to  
use it to isolate contacts of a relais (mains voltage). It shortet them  
right out in uncured state!.

Mythbusters did that, fragments shot one of the girls near the eye when  
one exploded... on camera...

I got black flexible hose.  It is made of foam rubber, the outside is  
smooth and has tiny holes punched in.
Works all right. I had to take out the lead wire in it (keeps it submerged  
but CuCl eats lead for breakfast).

My 110l/h pump is just a tad small for 45cm hose, need to get a bigger  
one, the last 5cm of the hose get no air. But no hurry..
