Put some Uranium 238 in a cloud chamber to see the radioactive particles [VIDEO]

Uranium-238 is the most common isotope of uranium found in nature, with a relative abundance of 99%. Unlike uranium-235, it is non-fissile, which means it cannot sustain a chain reaction in a thermal-neutron reactor. However, it is fissionable by fast neutrons, and is fertile, meaning it can be transmuted to fissile plutonium-239. 238U cannot support a chain reaction because inelastic scattering reduces neutron energy below the range where fast fission of one or more next-generation nuclei is probable. Doppler broadening of 238U's neutron absorption resonances, increasing absorption as fuel temperature increases, is also an essential negative feedback mechanism for reactor control.

Vaporizing paper in scary piranha solution [VIDEO]

"I decided to make some piranha solution, which is a mixture of sulfuric acid and hydrogen peroxide. It forms an extremely strong oxidizer that can vaporize most organic materials, like paper, into CO2 gas."

Why Hurricane Categories Make a Difference [VIDEO]

During a hurricane you usually hear meteorologists refer to its intensity by categories. If you don't know the difference between a category 1 and a category 5 hurricane, The Weather Channel meteorologist Mark Elliot breaks it down for you.

In 1859, this is how women typically dressed [VIDEO]

The fashionable silhouette of the 1850s was defined by a small waist, drooping shoulders, and a voluminous dome-shaped skirt that steadily grew in size through the decade, supported underneath by multiple petticoats.
