Can You Solve It? Are You Smarter Than a Soap Bubble?
Four towns are situated at the corners of a square, forming the basis of this puzzle. The goal is to find the road system that connects all four towns using the smallest total length of road.
Three different routes are presented: the O-loop, the U-route, and the X-road. Each route has its own drawbacks โ they're either too long or not optimal overall. However, there's one solution that combines the benefits of each route.
To find this solution, you don't necessarily need to delve into complex math. Instead, consider making a physical model of the puzzle using transparent materials and dowels. Submerge the model in soapy water and observe how bubbles form around the dowels โ they will reveal your answer.
The key is to recognize that the minimal road network resembles a simple, geometric shape commonly found in nature. When you've figured this out, stay tuned as our journalist will share their solution and the video of the soap bubble representation at 5pm UK time.
