Inspired by the global hackerspace movement and (software) hack days, Kids Hack Day is a 1-day event held in various locations around the world, where children and adults come together to “hack” and make new uses of every day items.

This incredibly charming video from the Kids Hack Day kickoff event in Moscow on May 25 shows you what it’s all about. (And, we are tickled to see our own WaterColorBot and EggBot making little appearances as well.)
