What doesn't get any wetter, no matter how much rain falls on it?
Common Wrong Answers
“A sponge”
A sponge absorbs water and becomes wetter when exposed to rain, so it does not fit the criteria of not getting wetter.
“A boat”
A boat can be affected by rain and will take on water, making it wetter, thus it does not satisfy the riddle's condition.
“An umbrella”
An umbrella is designed to keep things dry, but it itself becomes wet when it rains, which contradicts the riddle's premise.
