As the United States continued printing more and more paper money in the latter half of the 20th century -- backed by the very same amount of gold held by the United States Treasury -- by 1970 the percentage of each dollar that was actually backed by gold had fallen from 100% (in 1933) to 22%. That's why in 1971 President Richard Nixon removed the dollar from the gold standard. And, since that time, the actual value of the United States Dollar has has been whatever an individual has believed it to be worth at any given time, as the value of the dollar has not been guaranteed by anything of intrinsic value, such as gold or silver. The United States Dollar currently is not guaranteed as possessing any value whatsoever. It's simply worth whatever a person thinks it is. Although there are other factors, the removal of the link between the value of gold and the value of the dollar has been a major reason the United States Dollar is now only worth 10%-15% of its value in 1971.

Well, I'm not a crook. I've earned everything I've got." --Nixon about Watergate
Is food from the dollar tree edible. Let alone the cat food.
You can let the oil float to the top or you can use fairy liquid.
Just like Earth's gravity holds you to Earth, and doesn't let you float away, Mars, too, has some gravity (less than Earth), which won't simply let objects float away into space.
put a dollar bill on the road and let them leave
