What can happen when water is thrown into a volcano [VIDEO]

In some cases, the water can instantly turn into steam, causing a rapid expansion of gases within the volcano, potentially leading to an explosive eruption

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.
