[PSUBS-MAILIST] idea

[Alan via Personal_Submersibles]

Hank,
Could you not just scrape the jug along the bottom, then let the lid
Close on the contents when you place them back in the rack?
You have other problems like the containers floating away when you 
descend! Maybe metal containers with magnets on the base of their 
storage rack.
