The whole thing is purely conceptual for now; it involves certain bacteria and ice nucleation and a lot of other science-y sounding words and phrases I don't understand. What I do understand is the phrase "It will snow ice cream," and what I wish I didn't understand is "The technology is a long ways off." Don't be fooled by the existence of an actual Cloud Project van—it's purely for illustrative purposes, and only functions as a regular ice cream truck/science information center.

Plus there's talk of having a light beam that reflects off your enamel to determine how clean your teeth are and when you need to move on.

The spray is made up of microorganisms found on plants near undersea volcanoes. The logic seems to be that the microorganisms that are found on the plants have developed ways to protect the plants from the harmful radiation put out by the undersea volcanoes. Therefore if we coat ourselves with the same junk we will benefit in the same way. No word on price, but please don't buy this.– Ben Longo

Every fifteen minutes, this $60 device sprays a mist of "hospital-grade disinfectant" onto the knob, killing whatever post-urination/defecation residue got transferred to the knob after being handled by hundreds of people.

Those in the hygiene brigade can reel off dozens of reasons all strangers are potential enemies: virulent flu seasons, packed airplanes with stale air, buses where no one covers a mouth when sneezing. But social critics detect an element of hysteria in the germaphobia of Americans and suggest that at its root is a fear of a dangerous, out-of-control world.
