Exploring Chemistry with Fire & Ice

Exploring Chemistry with Fire & Ice

Can you change the speed of a reaction just by changing the temperature? That’s what we’re going to find out! First, we need to understand the reaction: This balloon is filled with hydrogen, and then it is lit on fire. This is known as a combustion reaction, where hydrogen combines with oxygen. This means that

What is a Superconductor?

What is a Superconductor?

Lots of materials are conductors, meaning electricity can flow through them. However, even power lines, which have the sole job of transporting electricity, aren’t perfect. A little bit of the energy gets lost as the electricity flows. This loss of energy is called resistance. Resistance isn’t a bad thing. We use it for a lot of

Liquid Nitrogen: Deep Freeze Science

Liquid Nitrogen: Deep Freeze Science

 It was a cold night in Russia’s Sakha Republic. Tiny Oymyakon, widely regarded today as the coldest town on Earth, was used to going about its business in near-arctic temperatures. On February 6, 1933, its residents braved the lowest temperature ever measured in an inhabited location: ninety degrees below zero, Fahrenheit.* Source: http://www.nasa.gov/sites/default/files/coldestplacerecords.png?itok=nAYJEo7W In

What does Liquid Nitrogen do to Balloons

What does Liquid Nitrogen do to Balloons

Liquid Nitrogen is a cryogenic liquid. It seems exotic because its extremely low temperatures cause it to affect things differently than we see in everyday life. To understand it a bit better, lets look at where it comes from. Nitrogen is a very common element. It makes up about 78% of the atmosphere, so you

Liquid Nitrogen & Glowsticks

Liquid Nitrogen & Glowsticks

 Note: Opening glowsticks is not a particularly great idea. They contain bits of broken glass and some unpleasant chemicals that can be hazardous to your health! Read full article to learn more. Glowsticks are incredibly fun, but how do they work!? Naturally because of some very cool science, notable chemistry. Glowsticks are made up

What to Freeze Series – Cryogenics

CAUTION: DO NOT TRY THIS AT HOME! LIQUID NITROGEN CAN CAUSE TERRIBLE BURNS! (Death of living tissue caused by the extreme cold.) Liquid Nitrogen can be scary. We call it a cryogenic fluid because it can rapidly cool substances down to temperatures around -321 degrees Fahrenheit. Unprotected human body parts are not immune to the danger

Liquid Nitrogen Pool Exploration

CAUTION: DO NOT DO THIS WITH SOMEONE IN THE POOL! IT IS VERY DANGEROUS AS THE EVAPORATED NITROGEN DISPLACES THE OXYGEN IN THE AIR AND SOMEONE COULD SUFFOCATE AND POSSIBLE DEATH. At AstroCamp, we love exploring and testing theories. So what do we do when we have excess liquid nitrogen from our summer camp program
