When you hear “Lego music,” you probably imagine the sound of stepping on a brick at 2 a.m., but this working LEGO xylophone is way more melodic! Every single part of this instrument, from the keys to the mallets to the string suspension, is made entirely out of official LEGO pieces. The keys are tuned using cleverly placed bricks underneath. Even the mallets are made from LEGO rods and tires. It’s basically Mozart meets Master Builder. Check it out!
