# A Game to Play While Skydiving

September 13, 2017

The Rubik’s Cube is that famous toy that you twist and turn to make each side all one color again. Kids and grown-ups race to see who can unscramble it the fastest. Well, this guy solved the cube while falling through the sky! He jumped out of a plane 13,000 feet above the ground, then raced to solve the puzzle toy in time to open his parachute. As we see in this crazy video, the ground looks very, very far below when Chris jumps. But he falls fast, so good thing he solved it in just 50 seconds. He opened his parachute in time, and didn’t have to go splat.

Wee ones: A cube has 6 faces (flat sides). Find a 6-faced box or cube shape in your room. Which face is on top? Which is on the right? On the left?

Little kids: Once Chris color-matched 3 of the 6 faces, how many faces did he have left to solve?  Bonus: If Chris jumped from 13,000 feet and solved the cube after falling 10,000 of those feet, how far above the ground is he now?

Big kids: Big jets from airports fly about 3 times as high as Chris’ 13,000-foot plane. About how high do jets fly?  Bonus: If Chris had started solving at 9 seconds and finished at 1 minute 9 seconds, at what time was he halfway through solving it? (Reminder: A minute has 60 seconds.)

Answers:
Wee ones: Items might include shoeboxes, toy boxes, or building blocks.

Little kids: 3 faces.  Bonus: 3,000 feet.

Big kids: 39,000 feet.  Bonus: At 39 seconds. He’d finish 1 minute later, so the halfway point was 1/2 minute after 9 seconds.

Her mom had Laura baking before she could walk, and her dad had her using power tools at a very unsafe age, measuring lengths, widths and angles in the process. Armed with this early love of numbers, Laura went on to get a BA in astrophysics from Princeton University, and an MBA from the Wharton School of Business; she continues to star-gaze today. Laura’s other interests include her three lively children, chocolate, extreme vehicles, and Lego Mindstorms.
