Peanut butter containers can be stored upside down to improve the spread’s texture.
Most peanut butter products use oils to extend their shelf life, but these oils tend to separate from the solid part and can cause a mess when you try to stir it back in. One way of avoiding this hassle is to store the peanut butter container upside down. This will force the oil to mix itself with the butter, resulting in a smoother, well-blended spread.
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?
