Apples & oranges
There are three boxes, one contains only apples, one contains only oranges, and one contains both apples and oranges. The boxes have been incorrectly labelled such that no label identifies the actual contents of the box it labels. Opening just one box, and without looking inside the box, you take out one piece of fruit. By looking at the fruit, how can you immediately label all of the boxes correctly?
The answer is to use almost all senses. With my eyes closed, I would touch all the surrounding fruits in the box to feel for all textures. Apples and oranges don't feel the same - apples are smoother and can feel a bit harder when squeezed. Oranges on the other hand have a bumpier texture with a spongier feeling when squeezed. Once I know the content of one box, I'll have two remaining boxes to identify. That's when i'll have to use my sense of smell to sniff out any answer, or I can carry the remaining box and shake them to hear for any particular sound that identifies the answer.
