Using a pendulum to figure out if someone’s telling the truth is like asking your cat to help with a math problem—curious, but not quite foolproof! Pendulums have been used for centuries in dowsing, which some believe can find lost objects or hidden water sources. Did you know that pendulums were first popularized in the 19th century by the fascinating, albeit eccentric, scientific minds of the time? While many swear by their pendulums for all sorts of mystical insights, it’s worth noting that modern science doesn’t exactly back them up. Instead of relying on pendulums, it might be more reliable to stick with a good old-fashioned heart-to-heart chat—plus, you won’t need to worry about keeping the pendulum from swinging off into the unknown!
