<P> The dry ice bomb device was featured on MythBusters, episode 57 Mentos and Soda, which first aired on August 9, 2006 . It was also featured in an episode of Time Warp, as well as in an episode of Archer . </P> <P> Following the Mars flyby of the Mariner 4 spacecraft in 1966, scientists concluded that Mars' polar caps consist entirely of dry ice . However, findings made in 2003 by researchers at the California Institute of Technology have shown that Mars' polar caps are almost completely made of water ice, and that dry ice only forms a thin surface layer that thickens and thins seasonally . A phenomenon named dry ice storms was proposed to occur over the polar regions of Mars . They are comparable to Earth's thunderstorms, with crystalline CO taking the place of water in the clouds . </P> <P> In 2012, the European Space Agency's Venus Express probe detected a cold layer in the atmosphere of Venus where temperatures are close to the triple point of carbon dioxide and it is possible that flakes of dry ice precipitate . </P> <P> Prolonged exposure to dry ice can cause severe skin damage through frostbite, and the fog produced may also hinder attempts to withdraw from contact in a safe manner . Because it sublimes into large quantities of carbon dioxide gas, which could pose a danger of hypercapnia, dry ice should only be exposed to open air in a well - ventilated environment . For this reason, dry ice is assigned the S - phrase S9 in the context of laboratory safety . Industrial dry ice may contain contaminants that make it unsafe for direct contact with foodstuffs . Tiny dry ice pellets used in dry ice blast cleaning do not contain oily residues . </P>

Where is dry ice used in the real world
