Call of the Mild
On a scale of outdoor bravado, I fall closer to Disney’s River Country then Sean Penn’s Into the Wild. But, I wasn’t about to let a lack of Eagle Scout skills keep from enjoying and evaluating a new backpack from Skull Candy. So this past Memorial Day, I took my own urban hike through downtown San Francisco from barbecue to beachfront. The Link Hydro Pack features two key components intended for the enjoyment by “mountain bikers, hikers and snow enthusiasts,” but easily altered to enhance a weekend of burgers, beaches and perhaps a few cold brews: speakers and a ½ gallon hydration pack. Appropriate usage of the hydration pack requires no direction or formal training. More tactful and subtle then the beer helmet yet equally potent, our chosen form of hydration remained chilled after several hours in the sun.

The Science of Sci-Fi
In the world of cinematic science fiction one of the most appealing themes involves a universe brimming over with intelligent life. In this imagined future (or past) humans interact with alien friend and foe because they've at last hammered down the ability to travel to distant stars and galaxies, and, yes, "to boldly go where no man has gone before. Having grown up on the original Star Trek series, observed the effect of the Star Wars movies on the zeitgeist of movie-going generations and enjoyed sci-fi soap operas like Battlestar Galactica, I have to admit I wish we could make it happen; no matter the odds.

The Instant Hot Tub
Self-heating soup sounds like something from the future: Push a button on the can, and three minutes later the contents are piping hot. But its widely available today, along with self-heating coffee and hot chocolate. In Japan, I even found self-heating sake. Pretty high-tech! Or not. In fact, these products use a chemical reaction known since at least 4000 B.C.—the mixing of quicklime and water. When you roast limestone at about 1,650�F, it converts to quicklime, a powder used to disinfect corpses in war zones. Mix quicklime with water, and it grabs and binds the water molecules, releasing lots of energy in the form of heat. (The material left over, known as hydrated or slaked lime, is the basis of lime mortar, popular in the Roman empire and still used today.) Soup is OK, but I decided to use the technology to make a self-heating hot tub.
