What is a slogan for Krypton?

One slogan for the element, krypton, is "the non-reactive gas that sometimes reacts". Krypton is a noble gas, similar to neon and helium, and the noble gases are mostly inert to reactions with other elements. However, krypton forms molecules such as krypton difluoride under certain conditions.

Krypton is a colorless and odorless gas with atomic number 36. It is one of the rarest gases on Earth and has limited uses. Like the noble gases neon and argon, krypton gives off a glowing light when exposed to an electrical current at low pressure. This white light is used in runway lights and photography. Krypton-85 is an isotope of krypton that is a by product of nuclear fission.
