Here’s another classic math riddle for you to prune your brain on a little bit: if people were lined up from tallest to shortest (meaning a person can see everything in front of them) and all wearing black or white hats, can you figure out which color hat you were wearing even if you had no idea how many black or white hats there were total? The answer is yes, you can!
Riddles can be fun but can also be really stressful when you start to feel your decently well-wrinkled brain shrivel into a prune. But hey! Tease the brain and the satisfaction of solving it outweighs the unnecessary stress added to your life, right? Right! Here’s the classic bridge riddle in animated form from Ted-Ed. How can you get a group of people across a bridge in a certain amount of time?
