Foam in bubble baths help regulate the water’s temperature.
Bubbles act as thermal insulators by blocking the water’s surface and preventing heat loss. One experiment confirmed this theory, and they found that the water with bubbles cooled down at only half the rate of its foam-free counterpart.
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?
