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.

Can music change how you taste? | Interactive Science Experiment | Do Try This At Home | At-Bristol

Can sounds change the flavour of food? Nerys & Sarah of the Live Science Team invite you to take part in an interactive science experiment at home: grab some headphones and tuck in to some science!

Tell us what you thought; did the flavour of the tonic water change? Try it with other foods and let us know what you experience.

Glow in the dark stars
Did you have these glow in the dark stars on your bedroom ceiling as a child? Fluorescence is the emission of light by a substance that has absorbed light; causing the electrons of that substance to jump between ground and excited states. Quinine, found in tonic water, is also fluorescent. Don’t believe me? Next time you’re in a bar with a UV light, order a Gin & Tonic to see for yourself. These stars continue to emit light after the UV light has been switched off, meaning they glow in the dark - this is known as phosphorescence. Find out how you can use this material to make phosphorescent graffiti in this video: http://youtu.be/T2vxb9YsfMk

Luminescence
When a metal chloride solution, dissolved in alcohol, is sprayed through a flame, this is what happens. It’s called luminescence & the light is emitted when the electrons of the metal jump up and down between an excited & ground states. Since each metal atom has a unique number & arrangement of electrons, the colour of light emitted from that metal solution is unique. Ever watched fireworks? That’s luminescence. And some of the common compounds used to create the colours of fireworks can be seen in this demo. Want to know more, check out the source video investigating the science of what makes something glow in the dark: http://youtu.be/T2vxb9YsfMk

Catalase
The liver is responsible for detoxifying your body. It accelerates the break-down metabolic hydrogen peroxide into oxygen & water, using the enzyme ‘catalase’. In this image you can see the effect of adding concentrated hydrogen peroxide to diced pig liver. The oxygen bubbles created can then re-light a glowing splint. See the full experiment in this video: http://youtu.be/lWcMox3e2Dk
