You’ve spoiled them with tot-friendly tech gadgets and custom-made pals, yet nothing captures their attention like a refrigerator box.

Foster their creativity with Shuttle Imagination, a biodegradable cardboard upgrade from KidsCraft Playhouses.

Made from 100 percent recycled materials, the precut, easy-to-assemble shuttle fits two to three mini moon walkers at a time. Orbital explorers can team up to decorate the shuttle’s blank white surface with crayons (think control panels, stellar discoveries, or mission names).

We recommend preparing for launch in a basement or backyard (unless you don’t mind a giant rocket in your living room). The best time to blast off? In the evening, when astronauts-to-be can view actual stars through a pair of portholes.
