Before there was texting, teenagers communicated with Morse code and tiny flashlights. OK, well, spies did, and ships at sea. And it’s time today’s kids learned Morse code anyway. This kit has a small push-button light with a Morse code chart on the back, plus a shutter card, a tiny version of the open-shut shutters that ships at sea used. Requires zero bandwidth, and fun for the STEM kid in your family. Also for the family spy.
