A Purple Fantasy: Bubbles at CosmoCaixa, Barcelona

Purple or magenta, the point is that this image is to be regarded more as an abstraction. I decided to follow one of those typical bubbles inside a lava lamp, you know, the ones that hypnotize and make you look like an idiot. The place CosmoCaixa again. This is more some sort of experiment and not exactly a lava lamp I guess but it reminds me of the old fashioned contrivance.

Plasma Ball Detail at CosmoCaixa Science Museum, Barcelona

This is a detail of a plasma ball at CosmoCaixa Science Museum. Many of you have seen these balls that seem like octopuses or aliens extending their tentacles whenever someone dares to touch the surface of the crystal sphere. It was hard to take this picture since I had to avoid the use of flash on the reflecting surface and I had no tripod with me at the moment to gain stability and look for more natural light in the dark pavilion. I hope you like the result. The tiny star-like spots are just reflections on the ball that I did not edit to keep the cosmic look of the image.

Now to enrich our scientific knowledge a little bit, a definition of

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
