I'm Ross, I'm a science presenter and video producer.



I mostly reblog stuff I think is awesome and post educational videos I've helped create.

Pouring an ice cube using supercooled water:
The temperature of the liquid water is reduced below its freezing point, without becoming a solid. The ice wont form without the presence of a nucleation point (a crystal or impurity around which an ice crystal can begin to grow). However, on contact with another surface, the water instantly freezes. Check out how to make instant ice at home in this video: http://youtu.be/sBFK5-JvBAc

Your body contains ~50 trillion cells, each cell contains 23 pairs of chromosomes, these chromosomes are made of over 3 billion base pairs of DNA, containing 20,000 genes, coding for millions of different proteins. Phew!

Why do things glow red hot?
Incandescence is the emission of visible light from a hot body as a result of its temperature. At roughly 400 degrees Celsius, the vibrating atoms within these hot coals glow with a red light. Despite the high temperature, it’s actually possible to walk across these coals due to their poor thermal conductivity. Find out more about the science of firewalking in this video:http://youtu.be/-iBFwpKV6ak

See-through skin
A ‘vein-viewer' works by using infrared light to image the presence of veins underneath the skin: The IR light is absorbed by the deoxygenated haemoglobin within veins. The locations of absorption and reflection are detected and the machine generates a corresponding projection using visible light. Find out more about how these devices are used in medicine in this video: http://youtu.be/lk0HMqwreIo

Alcohol rocket
Here you can see the ignition of ethanol vapour in a bottle. The wave of combustion travels up the length of the rocket, the rapidly expanding gas increases the pressure, and the resulting propulsion sends it flying! Find out how to make a rocket in this video: http://youtu.be/xGrzjikAA5U

Aperture & Astrophotography
In optics, an aperture is an opening through which light travels. A larger opening in the lens allows more light to your image. In astrophotography you’ll need the largest possible aperture to collect as much light as possible, this equates to a low f-stop number (e.g. f2.1). Find our more about astrophotography in this beginner’s guide to taking a photograph of the Orion Nebula: http://youtu.be/cPy79aWKOQQ

What’s inside a brain? | Brain Dissection | At-Bristol Science Centre

Why are brains wrinkly? Which animal has the biggest brain? Nerys of the Live Science Team delves into the grey matter of a pig’s brain to find out more about how our brains work.

This video was presented by: Nerys Shah, Live Science Team

Produced by: Ross Exton, Live Science Video Producer, and Seamus Foley, Big Screen Producer.

Corpus Collosum
This is the ‘corpus callosum’ of a pig brain. This structure contains millions of neural fibres connecting the left and right hemispheres of the brain, allowing them to communicate. In humans it is reportedly larger in people who are ambidextrous. Watch the full brain dissection here: http://youtu.be/U5_kckcYiCc
