Remember the Wonder Twins from DC Comics? If you're familiar with the extraterrestrial superheroes, then you know all about those rings they wore. They would touch rings and says "Wonder Twin powers, activate!" to ready their superpowers.
This homemade set of rings is reminiscent of those superhero rings, because when you touch them together, they sing! If you want to know how to make these makeshift rings, watch and learn and improve upon.
For this toy ring project, you'll need a musical greeting card, metal band, duct tape, copper, scissors, hot glue gun and a soldering iron.
