$\textbf{Stack of Coins}$
Can you fit a stack of quarter coins as high as the Empire State Building into a normal room?
$\textbf{Answer}$
Yes.
$\textbf{Analysis}$
The Empire State Building is about $100$-story high. Therefore, a stack of coins of that height can be broken into about $100$ stacks of coins. Each stack is about one story high (If we consider one story of the Empire Building is higher than one story of a normal room, then we can break the original stack into two hundreds piles). Now, it is obvious that the target is achievable.
$\textbf{Note}$
This type of brain teasers try to create a scary mis-perception. The best way to solve them is to keep clam and do the analysis.
