Hey guys I just found this video https://www.facebook.com/HappyPeopleHappy/videos/86646285674... and thought it's a good idea to use for cleaning round bottom flasks.

Pretty cool.
I used to clean the inside glass in large aquariums the same way. They actually make hard backed magnetic scrubbers for that purpose but this idea is
very cool.
It's in my "keepers" folder.
