Inside a Soda Can – Hidden Liner – Steve Spangler

You won’t believe what our science guy Steve Spangler found inside a soda can. In fact, it’s inside every soda can and it protects the aluminum from reacting with the soda. Steve takes us inside his lab for a chemistry lesson you won’t forget Continue reading

How We Know Black Holes Exist?

This video is about the astronomical amount of astronomical evidence for black holes, ranging from x-ray binaries with accretion disks, supermassive infrared-radiating galactic nuclei black holes, orbital characteristics of high mass binaries, and direct gravitational wave detection of inspiraling merging black hole binaries with LIGO. Yes, they’re real. Continue reading

LeChâtelier’s Principle and the Solubility of Carbon Dioxide

This activity demonstrates the effect of pressure and temperature on three reversible reactions: the solubility of carbon dioxide in water, the reaction of dissolved carbon dioxide and water to form H2CO3, and the weak acid ionization of H2CO3 to give HCO3- and H+ ions. For simplicity sake in terms of classroom discussion, these reactions are combined into one equation in Equation 1. Continue reading
