Calling all cubists: are you ready to do the Rubik’s Cube? If you were a kid in the 80s, you probably spent quite a bit of your time desperately trying to solve this puzzle. (My own brother eventually resorted to taking it apart with a screwdriver and put it back to together, colored piece by piece!) Well, if you can believe it, it’s been 30 years since the famous cube came on the scene and today, it’s being touted for its ability to engage kids in math and science. Schools across the country are honoring its anniversary via the You CAN Do The Rubik’s Cube program, which awards students for successfully completing cube-related activities. But you don’t need to wait for September to try it for yourself. The Talking Walnut is hosting a Rubik’s Cube giveaway and will award two lucky winners with their own Rubik’s Cube and solution guide. Simply send an e-mail to the site, and we’ll pick two names at random. Be sure to include your name and mailing address.
