The Truth About Gravity
That there is little to no gravity in earth orbit, such as at the International Space Station. Gravity at the ISS is about 90% of gravity on the earth’s surface. (likelysmarterthanyou)
But since they’re traveling rapidly perpendicular (roughly) to the pull of gravity, they’re essentially in perpetual free-fall, which gives the ILLUSION of near-zero gravity. (ayemossum)
Not a Drop
That you need to drink eight glasses of water everyday. I have gotten into arguments with people over that. “What if I have soup or fruit does that count?” “Nope, need to have eight.”
I have about 20 glasses in my house of all different sizes so which one does it need to be? No one can tell me or back it up. There is no scientific evidence that says “you must drink eight glasses of water to be healthy.” (mayfleur5)
There is no set amount, if I remember correctly the eight glasses bit came from an old National Nutrition Board recommendation and has just been repeated ad nauseam to the point of it becoming a hard rule.
The recommendation was for eight eight ounce glasses of water, but also noted that the majority of the intake could be achieved from food intake. Basically the real rule should be, if you’re thirsty drink water and avoid sugary drinks. (ammexico)
A few years back, Canada got rid of the penny so the smallest coin there is now is 5¢. If you pay cash, your total gets rounded to the nearest 5¢.
There were tons of people who freaked out saying prices were going to increase, most notably gas because they thought every item could only be a price that ends in a multiple of five cents (ex. every litre of gas would go from being 92.6¢ to 95¢). And others still, who while they understood that something was still allowed to cost $1.99 thought merchants would start a huge conspiracy to somehow make it that you end up paying more every time, that your transaction total would always be in a “round up” situation.
