Think

Think about how it all fits together with mind-blowing exclusive videos from Mark Rober.

Think

Thinking like an engineer means you're resilient. It's getting back up after being knocked down and approaching things differently. That determination helps kids tackle everyday challenges and it's the same determination that puts rovers on other dang planets!

Best gift! He had the box open and was building within moments of receiving it. Then he showed his siblings and his neighborhood friends just how cool it was!
