Aaron Keller, Chemistry teacher, demonstrates the amazing properties of liquid nitrogen. He explains each demonstration in an understandable way. The temperature of liquid nitrogen is -196C (-321F). He explains how a dewar flask works. He pulls balloons out of a cooler, showing the expansion of a gas as it warms. He demonstrates the explosive power of the expansion of liquid nitrogen in an enclosed container. Liquid nitrogen is so cold that the floor is like a hot griddle. Liquid nitrogen has a very low viscosity. He demonstrates how brittle a flower becomes when frozen in a liquid nitrogen bath. Finally, he shows how to shatter a racquetball. As a bonus he shows how nitrogen gas can be used to put out a candle flame.

UNSAFE, NOT FOR KIDS! Main article: bit.ly amasci.com Can't get liquid nitrogen? Then make your own -80C/110F version by using Dry Ice. Note that this science demonstration involves several major safety hazards, and should only be performed by skilled educators. If used for science fair projects, close parent/teacher supervision is required. But also go see bit.ly SFGATE: "The War On Curiosity" (stamping out hobbyist science in order to keep kids safe.) For lots of suggested low-temp physics demonstrations click on the above link. Or, look on the web for liquid nitrogen demonstrations. Note that dry ice comes from companies listed in your local yellow pages. Some welder supply stores carry it. In Seattle, you can find it in the seafood section of QFC neighborhood grocery, and at some Fred Meyer stores. Ask for dry ice pellets rather than slabs, so you won't have to chop it up yourself. .

I go back to sticking my hand into liquid nitrogen but remain uninjured due to the Leidenfrost effect. The Leidenfrost effect is the formation of a gas barrier between a hot surface and a boiling liquid if the temperature difference is great enough. This gas barrier greatly slows the heat transfer between the two and allows the liquid to last longer and consequently the hot surface to remain hot longer. This effect can be seen in a frying pan as it's being heated. At first the water quickly boils as it's dropped in but at a hot enough temperature the Leidenfrost effect takes over and makes the water skate around the surface lasting a very long time. Liquid nitrogen vs. a room temperature object will also exhibit the effect preventing it from instantly freezing the object... such as my hand.

Complete video at: fora.tv Chef Ferran Adria, head chef of elBulli, and Harold McGee, author of On Food and Cooking, describe how liquid nitrogen is used in restaurant kitchens to create innovative dishes like alcohol sorbets and frozen pistachio puree truffles. ----- No one can get into elBulli, Ferran Adria's restaurant on the northeast coast of Spain. But plenty of people certainly try: every year, the restaurant receives over two million requests for only 8000 seats during the six months it is open. For the other six months, Adria, who is proud to be called the "Salvador Dali of the Kitchen," travels, dreams, and creates at his "food laboratory" in Barcelona, called elBulli Taller, where his team includes a chemist and an industrial designer who also design plates and serving utensils to go with the food. No wonder, as Corby Kummer wrote in The Atlantic, "making the twisty two-hour drive from Barcelona for a dinner that ends well into the wee hours has become a notch on every foodie's belt--perhaps the notch, given the international derby to get reservations." For mortals who won't be making the trip soon--or who didn't hit the lottery last year in the German contemporary-art exhibition Documenta, which flew two people at random per day to el Bulli to experience "the exhibition" that is dinner at elBulli--Adria has given the world A Day at elBulli: An Insight into the Ideas, Methods and Creativity of Ferran Adria.

Here we freeze acetone with liquid nitrogen. This is a little different from freezing water because the mist produced is very dense and you can actually scoop it up in your hand very easily. I'm not actually touching liquid nitrogen, I'm just touching the acetone mist above it. Also when it freezes the acetone becomes a snow rather than just creating a sheet of ice like in water.

Dr. Undergrad presents a basic introduction to the Nitrogen Fixation Cycle. In this cycle nitrogen is fixated to become more biologically available to the organisms of the world. Nitrogen from the atmosphere will be fixated into a nitrate or the ammonium ion. Once fixated there are a number of processes that the fixated nitrogen can undergo to pass through the cycle until it returns back to the atmosphere. This video was made for a contest hosted by www.chlorofilms.org. Special thanks to Dr. Adán Colón-Carmona for suggesting the nitrogen cycle as a topic for the new animation.

READ HOW IT'S DONE HERE! ( www.popsci.com ) Boing Boing Video teams up with PopSci and Theo Gray ( MAD SCIENCE author) for an eerily beautiful science experiment -- how to cast solid, if fleeting, shapes from normally liquid mercury -- just keep it at 320 degrees below zero, with liquid nitrogen. Snip from Theo's experiment, documented in this video: "What you consider solid, liquid or gas depends entirely on where you live. For example, men from cold, cold Mars might build their houses out of ice. Women from Venus, where the average temperature is about 870°F, could bathe in liquid zinc. We think mercury is a liquid metal, but its all relative. At one temperature, the mercury atoms arrange themselves into a solid crystal; at another, they flow freely around each other as a liquid. Children from Pluto (like mine, for example) could happily cast their toy soldiers out of mercury, because on that frigid planet it is a solid, malleable metal a lot like tin. Here on temperate Earth, you need a stove to cast tin, but a tank of liquid nitrogen to make mercury figurines..." www.popsci.com RELATED BOING BOING BLOG POST: www.boingboing.net

Inspired by Bill Beaty's video and website, my own version of the poor man's liquid nitrogen. Dry ice is put in 99% methanol allowing you to do experiments similar to the standard liquid nitrogen experiments. It will freeze flowers, leaves, small fruit or vegetables as well as some plastics and rubbers. DO NOT TOUCH, this stuff will burn your skin almost instantly. DO NOT EAT, you can freeze food items in this but the methanol is poison and will kill you or make you sick so you can not eat them. NO SMOKING, methanol is flammable and everything you put in will come out with a flammable coating of alcohol.

When first learning about the nitrogen cycle it can be pretty confusing! Hopefully, this movie is easy to understand and can make fish keeping for beginners easier! Once you know this cycle, it's pretty easy to cycle it. Just introduce a form of ammonia (fish food, a frozen shrimp overnight, a few hardy fish, or PURE ammonia for example) and the rest is testing for ammonia, nitrite and nitrate levels. Once most chemicals are cleared you can (slowly) add your fish to the aquarium!! If you have any questions, comment below of send a message! Music: Blue Eyes by Mika

2 holes are punctured at a slanting/glancing angle into a ping pong ball. It is then immersed in liquid nitrogen. The air inside it cools. This lowers the air pressure inside the ping pong ball. Liquid nitrogen then partly fills the ping pong ball. The ping pong ball will start to spin as cold liquid nitrogen boils, shooting out cold nitrogen gas from these 2 holes and propels the ping pong ball and rotates it on a vertical axis

We take cubes of regular ice and cool them with liquid nitrogen. The ice made this way can be used to cool drinks and as long as you don't let the ice directly touch your mouth the drinks are safe. Once they warm back up to 0 degrees they can be treated exactly the same as regular ice. Alternatively, just use a straw when using ice of this type.

What's forbidden is the 'fraudulent alteration and mutilation of coins.' There's nothing fraudulent in what we are doing. We aren't trying to make pennies look like dimes or something. There are plenty of (legal) machines at amusement parks and fairs that'll happily smash one of your pennies into a souvenir.

Peak Moment 167: Nevada County locals Jim Wray and Loraine Webb show us the how and why of packaging bulk foods with nitrogen. They're using equipment available for community members to use at minimal cost. Jim demonstrates packaging: make plastic bags using a heat sealer, fill with foodstuffs, suck out the oxygen with a small vacuum, then replace the air with nitrogen and seal. Loraine, organizer of The Neighborhood Readiness Project, has arranged with several locally-owned grocery stores to sell 25 pound bags of grains, beans and other bulk foods at just above cost. Loraine's vision is our having food caches in every neighborhood in the county, so that, if the trucks stop rolling in an emergency, we'll have food for ourselves AND to share with our neighbors.
