If you ride your bike at night, you really should be lit up. Spend an evening at this fantasy maker studio (which feels like you shrunk down and are living inside a giant, well-stocked toolbox) to follow along and add a battery-powered strip of bright LEDs to your handlebars. There's also a follow-up session where you can sew on a pouch to make it waterproof.
