Long & Short by Classicho & TCC
To resurrect an age-old magic trick, we traced its origins and discovered a variation that has been overlooked but is incredibly clever. Historical records tell us that this prop was first crafted by P&L back in 1934. It was a fantastic visual effect known as the "Stretch-It Boom-E-Rang c." The trick capitalizes on the illusion created by geometric arcs and the psychological sway of magic, making the audience experience the magic's sense of wonder. The effect involves the magician displaying two identical curved boards, and then continuously making one of them appear longer than the other.
Later, in the late 20th century, Haenchen and Viking also put their spin on this effect, but the principle remained the same, with only adjustments made to the final size. Even today, this effect is included in various children's magic sets because of its interesting principle and simple operation, making it popular among the audience.
