In a rural area of Myanmar, two little kids are happily playing with a simple but clever toy that mimics the basic principle of communication. They use two small free cans connected by a thin piece of string. One child speaks into one can, and the other listens through the other can. When the string is taut, the sound travels from one can to the other, allowing the children to "talk" to each other over a short distance. This playful experiment demonstrates a fundamental idea that inspired the development of modern telephones. It’s amazing to think that such a simple toy can connect to the sophisticated technology of today’s smartphones.
