I’m a bit of a TED Talks addict. The topics are diverse, surprising and always interesting. For a small investment of time (the talks are generally less than twenty minutes) you will most certainly learn something new, memorable and thought provoking.
When I stumbled across Arvind Gupta’s TED presentation about how to turn rubbish into toys, I was amazed. Gupta shows how simple materials that are often thrown into the rubbish can be made into well-designed toys that kids can build themselves. And if that isn’t clever enough, building the toys also teaches basic principles of science and design at the same time. Bits of rubber tubing and matchsticks are the basis for a geometry or biology lesson, straws become a centrifuge and a pencil becomes a fan.
