By the way, put the rock in the basket FIRST then cover it with the hair net. That way you don’t have to sift through a nasty/dirty hairnet to retrieve your rock. Here in the desert we have the Arizona Bark Scorpion and it’s a painful little bugger to get stung by. Scorps can survive for a very long time submerged.
Just a suggestion....
Ahhh, that is a good idea. I guess all those years at MIT payed off in a random idea here-n-there!
