YouTube Roundup – Heating Things Up

Although the effects of the polar vortex over North America have largely dissipated, another major cold front has settled in over much of the U.S. The relief of the summer sun may seem far away, but the Internet is full of videos displaying more… exotic sources of heat. Find a blanket, grab a cocoa, and watch the action of some of science’s hottest materials!

The good folks at Carsandwater have a blowtorch, a source of nickel, and a seemingly endless supply of destructible objects. Considering the melting point of the metal is 1453 degrees Celsius (over 2600 degrees Fahrenheit), the red-hot nickel ball (RHNB) usually meets little opposition.

The aptly named YouTube account Lavapix creates mesmerizing shots of the liquid rock that oozes from the volcanoes of Hawaii. Here, a can of Coke boils almost instantly as it comes into contact with the lava flow.
