The Alexander Piano

A curious 15 year old ended up creating the longest grand piano in the world after asking a simple question. 

Inside a piano, the bass strings are wrapped with copper wire to deepen the sound without needing more length. A young pianist named Adrian asked his piano teacher, "without using copper wire, how long would the bass strings need to be to hit the right notes?" His teacher had no idea, so Adrian decided to figure it out himself. He purchased some piano wire and strung it up in his backyard. It was around 22 feet and the sound was amazing. Inspired by the incredible sound quality, the next step was to build a huge piano to hold the length of the wire and keep the amazing sound. Over the next 5 years, he came across difficulties that required a lot of problem-solving and dedication. But finally, his hard work paid off and his piano was complete. The Alexander Piano is 18ft 9 inches, weighing over a metric ton and is the world's largest single keyboard grand piano.
