Mentalism effects are considered to be the strongest ones in magic. Reading the spectator's mind, correctly guessing the card they are merely thinking of, or calling out the name of the person they are close with. These types of effects always leave the spectators with a great memory.
At first, mentalism can be perceived as easy due to a general lack of sleight of hand. The hardest part of mentalism is the performance side. Performing a mentalism routine with the desired outcome and effect takes practice. But don't be scared by that. If performed right, you can leave your spectators with an unforgettable experience.
What's great about most mentalism routines is that they can be performed for any audience size, close-up, or on stage.
