Answer: a mind (and toe, and finger, and just general body) numbing -100°C (or -148°F!). Where is this place, and what does it mean to you? Well, the coldest place on Earth is known as “Dome A,” or “Dome Argus,” and is located in the middle of Antarctica. It is known as the summit of the “East Antarctic Ice Cap,” which is in essence a large “mountain” of ice in Antarctica. What this means to you is that you would probably freeze to death in seconds if you went there unprotected (never mind the elevation and oxygen issues).

What is interesting to note is that dry ice (frozen Carbon Dioxide) is generally kept at around –78.5°C (or -109°F). This means that if you brought a block of dry ice to Dome A, it would actually get colder. We sure do live on a crazy planet!

To check out some substances that are actually hundreds of degrees colder than Dome A (or dry ice), check out the new Orlando Science Center show Sub-Zero, playing every Saturday in July.
