Engineer a gravity-defying glow string shooter that’s part physics experiment, part art installation, and all awesome. Build the base, construct a set of dueling motors, and add a strip of UV LEDs to get glowing. Then fire up your finished shooter, and watch it make a loop of string stand up straight in the air! Explore momentum as the string curves around your hand, or toss a flying disc through the loop to a friend. Then learn about UV light — all while lighting up a love of physics and engineering!
