Cling wrap and foil boxes have push tabs on the sides to prevent the roll from falling out.
Good news: you’ll never have to worry about the entire aluminum foil roll falling out of the box every time you try to tear it. Foil boxes come with these tabs on the sides, which are meant to keep the roll in place. All you need to do is push them before using the foil for the first time, and those ingenious built-in locks will keep the core steady.
smarter individual would use the other hook instead of a key....
Just screw it in by hand, it isn't that difficult.
#2 not sure it would work. cars have safety glasses which prevent shattering. you can buy special purpose hammers though.
WTF? Spell much?
