While researching ways to detect explosives at airports, Paul Edmiston, a chemist with the College of Wooster, made an unexpected discovery: a new spongelike material he calls "Osorb." The material soaks up oil and other contaminants from water, Miles O'Brien reports.
In this video, Edmiston shows how to whip up a batch of the stuff, adds toxins, filters them out and then drinks it.
Miles reports for the National Science Foundation's* Science Nation.
