Sea Urchin Skeletons or Tests at CosmoCaixa, Barcelona

What looks at first sight like a submarine photograph, the kind you would see when those robots scan a deep oceanic bottom with their spotlights is nothing but a cross section inside a crystal box full of sea urchin skeletons or tests at CosmoCaixa, an interactive science museum in the upper side of Barcelona (address: Teodor Roviralta, 47-51). Cosmocaixa is modern in design, and good in quality but above all it is fun for kids who discover that science is not just a boring book with entertaining pictures here and there, but a fascinating world full of mysterious experiments, amazing optical illusions, curious instruments and what is best, things they can touch and play with to obtain magic results. If you come with your children to Barcelona this museum is a must. This is a Google Earth snapshot where you see CosmoCaixa's location and also a closer look. As to my picture and sea urchins, I thought this cross section offered nice textures and made you think in a way about evolution of species and science.

Here is a short video to get an idea about the experiments: Defying Gravity
