Knowing your weight can be more of a mental exercise than merely a physical outcome. Well, it does sound exciting, but this weight machine will fascinate you more with its brain training potential for calculating body weight. Korean designer Seungyun’s innovation dubbed “Math Weight” lets you know your exact weight, but only after you give correct answers to mathematical puzzles it asks. This cool and intelligent design is created for sharpening the brain that mingles some mental work with a simple physical machine. You are required to apply basic mathematical operations of addition, subtraction, multiplication and division to compute four logical problems before you get to know your actual weight. The puzzles are displayed on the screen as soon as you climb on the Math Weight, thus starting the mathematical game show storming your brain. This intellectual design is being suggested to the State Education Commission for mental training and skill development of primary and secondary school students in a strangely innovative way, making use of the “know your weight” riddle.
