About This Project
The Guinness Book of World Records says the longest FUNCTIONING tin can phone was made by someone in Japan in August 2019. It went 242.626 meters, or 796 feet! That’s almost three football fields long! Sadly, there’s no details on how the phone was made or what materials they used, but maybe with some experimentation you can recreate their success at home. Be sure to hold the string as taut as possible for the best results, and experiment with a variety of materials to see what works best for you.
