Junior Engineer Kit
Design. Build. Test It Stronger.
Price to be announced · one-time purchase, no subscription
A builder's site in a box. Junior engineers use connector beams, gears, pulleys and string to build a bridge that holds weight, a working crane, a catapult and a tower that stands up to the "earthquake test". Blueprint cards show the goal, not every step, so children plan, build, test and improve. The Engineer's Logbook records every load test and every better idea.
