Insects (Class Insecta) are a major group of arthropods and the most diverse group of animals on the Earth, with over a million described species—more than half of all known living organisms with published estimates of undescribed species as high as 30 million, thus potentially representing over 90% of the life forms on the planet. Insects may be found in nearly all environments on the planet, although only a small number of species occur in the oceans where crustaceans tend to predominate instead
The Amazing Dry Ice Experiment
One of our readers just sent in an interesting (scientific) video clip that shows what happens when you combine dry ice with liquid soap. Watch after the jump.
Dry ice is produced by compressing carbon dioxide gas to a liquid form, removing the heat produced by the compression (see Charles's law), and then letting the liquid carbon dioxide expand quickly. This expansion and the high-speed evaporation of carbon dioxide gas cools the remainder of the liquid down to the melting point, where some of the CO2 freezes into 'snow,' which is then compressed into pellets or blocks
