Beer, Ice Cream, Movies and Video Games

PopSci's booth at Maker Faire was a crowd favorite (and we're not just saying that)—mainly because the projects displayed by contributors John Carnett and Theo Gray were both ingenious and superfun.

Want to make ice cream in 30 seconds, using liquid nitrogen? No problem.

How about an automatic beer-making, storing, and pouring machine? You can make one.

Think watching movies in the backyard would be fun? We do, too! All the projects definitely struck a chord with the Austin audience. Next year we'll bring some scantily clad punk-rock fire dancers and a bike modded out with LED lights, and we'll be a total shoo-in. —Megan Miller
