Hi Reddit! Kevin is a surface scientist with a Ph.D. in chemistry from Johns Hopkins and an expert beer homebrewer. Craig is a science writer and editor for Chemical & Engineering News with a background in inorganic chemistry who brews kombucha and hard cider. After seeing some fake helium beer videos online, Kevin and Craig got into a discussion about whether it would be possible to do it for real. Their calculations suggested it was feasible, so they gave it a shot. You can read about the results, and get the recipe, at http://cenm.ag/heliumbeer We’ll be back at 12pm ET to answer your questions! Edit - We are here to answer your questions!
