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.

"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."

Doner kebabis a type of kebab, made of meat cooked on a vertical rotisserie. Seasoned meat stacked in the shape of an inverted cone is turned slowly on the rotisserie, next to a vertical cooking element. The operator uses a knife to slice thin shavings from the outer layer of the meat as it cooks. The vertical rotisserie was invented in the 19th-century Ottoman Empire, and has inspired similar dishes such as the Arab shawarma, Greek gyros, Canadian donair, and Mexican al pastor.
