Tokyo Scientists Create Mobile Slime 111
Sockatume writes "Shingo Maeda and colleagues at Waseda University have created a polymer gel that walks under its own chemical power. The team exploited the oscillating Belousov-Zhabotinsky reaction to create periodic changes in the size of the polymer, and built a tensed structure that would amplify those small movements into a horrifically potent gait. The current version only walks across a notched surface, but the team are working on a terrible new form that will cross smooth surfaces like a snail. The team say they intend to apply it in the self-assembly of small structures. Suddenly, I can't stop screaming."

...An essential aspect of the BZ reaction is its so called "excitability" â" under the influence of stimuli, patterns develop in what would otherwise be a perfectly quiescent medium. Some clock reactions... can be excited into self-organising activity through the influence of light...
Well, looks like the power-transmission problem is solved - just shine a flashlight on the thing.

Hang on a second. That's not exactly a common mix. Was this guy trying out for the "Most Random Acid Cocktail" award?
