A kite messenger is a clever little device that slides up a kite string, releases a light payload, then slides back down to the bottom of the string for more fun. I made one with some cheap materials and finally found some windy days to test it out. Some kite messenger designs use sails to pull up the kite, but I’m starting out with a simpler design that uses toy parachutes to catch the wind. It can be made in just a few minutes using drinking straws, wire, tape, and a toy parachute.

Here’s how it works: The front loop of the wire hits a simple cardboard bumper attached high up on the line. As the wire stops, the rest of the unit continues forward, opening the middle section where the parachute is held. Once the parachute releases, the messenger slides right back down towards the spool of string, ready to be reloaded for more fun.

 

It’s fun to see the kid’s excitement build as they watch the messenger climb up the string, eagerly awaiting the parachute’s release so they can chase it down.
