You could take it to the next level and get a CO2 tank. With the lid on the bucket, opened just far enough for the hose to get in, slowly fill the bucket with CO2, which is heavier than air. Gently remove the hose and seal the bucket.
Or as I fantasize - when zombies attack and all we're left with are our shaving gear. No way I'm fighting them with stubble! With the shops closed, it's nice to have a stockpile.
Dang straight! If you watch the documentaries movies and TV shows, zombies always have stubble. If you are clean shaven, the good guys can recognize you as a good guy, too, and know not to shoot you!
Precisely! And what's better than a clean shaved face, smelling of Aqua Velva when slaughtering those creatures?!
Gamma Seal lids... I had never heard of those before, but they look very useful. A five gallon bucket seems like a lot, how many blades do you have? The Hydrosorbent and similar silica gel packs are relatively inexpensive and can be "recharged" by baking them in an oven. That way they can be reused pretty much forever. The Hydrosorbent website is at http://www.dehumidify.com. Military surplus stores often carry this or similar reusable silica gel packs. Here is one on Amazon. My take is that the shavepocalypse applies more to any particular cartridge razors and electric razors than to safety razors and double edge blades. As applied to traditional wetshaving gear, it might just be something to generate sales at online shaving stores. Of course, that is just my view based on my own experience.
Thankfully, penguins are immune to all but the Arctic strain of zombie-ism and at that, they tend to recover.
Precisely why I've got a dozen vintage straight razors and still working the RAD for more. If zombies are involved I'm going down like Sweeney Todd
