The 2 liter bottle of coke I once froze exploded with so much force that I found the freezer door open when I investigated the loud bang at 3am. No way a ziploc would contain that force.
I shared the link to this to friends a week ago or so.

Thanks. I did remember that US subs used a off the shelf controller but couldn’t think of the specific example.
Additionally with an off the shelf controller it’s really easy to pack a replacement one. (And building a controller yourself - that one will always be worse and heavier than an off the shelf one plus replacement)
The crazy thing really is how they ignored everyone on warnings how not to construct a hull.
Oooh, 3D printed mole crap.
