This puzzle can simply test how quick one can think, try to solve it in less than a minute. You can actually try this with your friends at a party. Ask them to place a pencil on the floor so that no one can jump over it. If they can pull it off, they’re really clever. It’s a simple trick, you just have to think practically to not let anyone jump over the pencil you placed. We most often look for solutions based on the questions we pose, instead try thinking for solutions outside the question’s context. In this case, an object to prevent people from jumping over the pencil. Placing the pencil under something like a refrigerator can work too but a much efficient solution is to place it near a wall out in the open. Anyone who wants to jump over it would give up the moment they know what you’re up to, as you have already placed the pencil strategically near the wall preventing them from jumping over. Although, it would seem absurd to place the pencil under a table or an object which could obstruct ones moment even before they attempt a jump.
Place the Pencil close to the wall.
