YouTuber Grant Thompson, The King of Random, recently posted this video on how to make your own batch of dry ice at home. The process requires a food-safe CO2 fire extinguisher (which he got for free at a local fire equipment servicing company) and a pillow case. The result is the solid form of carbon dioxide, which can be used for halloween effects, science experiments, or driving an engine. [via Gizmodo]
