Hula-hooping robots

Scientists built hula-hooping robots to answer an old mystery: How does a Hula Hoop stay up? Learn how best to launch and maintain a circulating hoop — and then explore how specific shapes can turn gyrations into a gravity-defying force. You can apply those concepts to then predict the hula-hooping success of other shapes.

    The case of the haunted railroad

    Strange ghostly blue lights have haunted the little town of Summerville, S.C. for decades. Reports of spectral balls of light floating along a desolate stretch of railroad inspired a ghostly local legend. Learn how legends can inspire real-world science. Then discuss similarities and differences between scientific theory and legend while answering questions about a proposed geologic explanation for this phenomenon.

    Where force fields collide

    Scientists have long suspected that a mysterious third force underlies the unique life-sustaining conditions of our planet but lacked the technology to measure it. Until now, that is. Learn how the interplay between different planet-wide energy forces gives rise to Earth’s cozy atmosphere. Then, explore how scientists use modern technology to study a newly discovered electrical field and fit this knowledge into their global understanding of how our planet supports life.

    Spinning spaghetti into nanonoodles

    Take a seat, “angel hair” pasta. Scientists just fine-spun the world’s thinnest spaghetti. This nano-noodle recipe calls for modern electrospinning technology blended with creative culinary science — and, of course, a handful of pasta dough. Learn how electrospinning works by comparing the technique to the function of an old-fashioned spinning wheel, at the same time answering questions about polymers and connecting chemistry concepts to textile manufacturing.
