Mentalism is like a magic show, but instead of doing tricks with cards or pulling rabbits out of hats, the mentalist uses their mind and your mind to do amazing things. Imagine you tell the mentalist to pick a number between 1 and 10 and they correctly guess the number you chose without you telling them. That's mentalism!
Sometimes they use special techniques like body language, tone of voice, or pattern recognition to figure out what you're thinking. Just like when you try to guess what your friend is feeling based on how they look or sound. Other times, they might use their own mind to read yours - this is called telepathy.
But mentalists aren't actually mind-readers, they're just really good at paying attention and noticing little clues that most people miss. They use these clues to make educated guesses that seem like magic tricks or psychic powers.
So, when you see a mentalist perform, remember that they're just really good at noticing things, guessing and putting on a show for you to enjoy!
