Went to the local chain picked up an anchor bubbler.... Saw the same one Floyd got, but it was cracked in 4 or 5 pieces.
I noticed this one, I had once had a bubbler made of a same stuff. $6.59... I know big spender!!! right??!! could have gotten the $1.59 stone, no no not for my UAS test!!!
The funniest thing was buying something called "anchor" and having it float like a champ! LOL
just testing it in the water now, and I think I may have found the best one for the job!!!
Nice perfect even controlled bubbles, in a perfect line!!! Off to go make a screen!!!
