if you pee in the trash can, you still dealing with pee sprinkles so you have to slow down your urine stream...the bottle catches the pee sprinkles...
my intention wasn't to make you feel like a pos and om sorry if eye did
pissing in a run of the mill empty 2 liter of soda bottle for instance, due to physics, it's a little tricky and eye could cee your apprehension....a lot of margin for error!
but this empty 16 ounce glass wide mouth bottle that was originally for Sea Moss jelly, eye think an intoxicated man could handle it....just have to make sure you hold onto the bottle like your life depends on it
