A YouTuber called MEZERG created a viral electronica song and corresponding music video called “Watermelon”, in which he plays slices of watermelon. The device, called a Playtronica, works on smartphones and tablets provided you have the correct adaptor and a music application such as GarageBand.
It’s compatible with most synths and musical gadgets with a USB MIDI input. Simply connect cables to your fruits and veggies, and complete the circuit by touching the ground wire with one hand and note wire with another. Watch his video below.
