How "Cold-Blooded" Animals Survive the Cold
We humans can rely on our internal body heat to help keep us warm. But what can cold-blooded animals do when faced with the threat of freezing? Here are three creatures that have come up with some...“cool” solutions.

Flamethrower vs Aerogel
We put aerogel to the test vs 'not-a-flamethrower', a huge 2000°C flame to a large fiberglass blanket infused with silica aerogel - formerly the lightest solid (that title is now held by graphene aerogel).

Liquid Nitrogen Demos
We look at how different materials change when they are exposed to liquid nitrogen. Flowers become frozen and stiff and the petals snap. A banana hardens and is strong enough to be used as a hammer and a squash ball becomes very brittle...
