The Marble Puzzle (A Short Lesson in Physics) Kids love digging into history to discover what games they played before the age of batteries. This puzzle is a great example, as it teaches kids about physics while providing endless fun. The idea behind this puzzle is simple: maneuver two marbles into their own homes at the end of a slope. Sounds easy, but due to the angles involved, it's impossible to solve by just tilting the unit. To succeed, kids need to apply forces on both marbles in the direction of their destinations. Tilting works perfectly for the first marble, but the second one requires more thinking. Imagine how a centrifuge works its magic... twist it! (Keep this secret safe.) If you have larger or smaller marbles, simply scale up or down to create a custom puzzle. For more pre-battery age kid-friendly designs, search Thingiverse for "willemvd".
