While preparing to give a presentation in Las Vegas, I was playing with liquid nitrogen to develop some new experiments that might work on stage. First I made a liquid nitrogen geyser (watch it here) and realized that the pressure change as liquid nitrogen turns to a g...

 I was snowmobiling through Yellowstone National Park and made a stop at the world famous Old Faithful Geyser. The family and I stood in two feet of snow in the frigid winter air watching as hot water and steam gushed from Old Faithful like a jet engine gone mad! Immed...

Liquid nitrogen is one of my favorite compounds in the science lab because it is so cold (-321 deg F) and readily available. Nitrogen is all around us, in fact the air we breathe is about about 78% Nitrogen! But, at standard temperature and pressure (STP) nitrogen is a...

Let me start here: this was not one of the best ideas I've ever had! I was preparing for "The Science Spot" a short science bit I do for the local CBS station and was deciding what liquid nitrogen demonstrations I should perform on tv. I stopped at the grocery store an...
