Super Hydrophobic Surface and Magnetic Liquid #The Slow Mo Guys
Gav and Dan are in the GE lab using nanotechnology to show you cool liquid physics at 2500fps.
The first experiment shows a superhydrophobic surface that GE has been working on. Surfaces like this can be useful in aviation and wind power to reduce ice build-up or for self-cleaning applications. The surface traps a layer of air using its nanoscopic structure, which prevents water from sticking.
The second experiment also demonstrates how the nanoscale differs from the macroscale, this time with iron filings. Iron filings at the macroscale can be easily distinguished from the liquid they are in. When reduced to the nanoscale, magnetic nanoparticles can behave like a liquid magnet. Gav and Dan demonstrate this by showing magnetic liquid flowing upwards against gravity towards a magnet.

Electric Bicycle *Bike #After Two Yrs on The Run
Made this video as a quick review of the conversion kit going into my third year of use. The beginning covers the review, not too much to say really, everything is still running top notch. The rest demos my lighting system plus other gadgets I have installed on the bike.
Samsung Sells 110-Inch TV for $150,000 #The World's Largest Ultra HDTV
Samsung said a 110-inch TV that has four times the resolution of standard high-definition TVs is going on sale for about $150,000 in South Korea.
The launch Monday of the giant television set reflects global TV makers’ move toward ultra HD TVs, as manufacturing bigger TVs using OLED proves too costly.

The Truth About Gingers
There are many names for them, but here at SciShow we lovingly refer to them as 'Gingers'. In this episode, Hank explains what gene is responsible for the creation of redheads.
