sensation

A sensation is an exciting or unusual experience that grabs your attention.

When we say "sensation," we often talk about how something feels. For example, going on a roller coaster can give people a big thrill and be a real sensation because it's so intense. Or maybe you've tried some new food that's become a huge hit with everyone - that could also be a sensation because of its unique taste or flavor. Sometimes we even use the word to describe a famous person, like a movie star, who's suddenly become very popular and is in every newspaper and magazine - they're a sensation!
