Intricately layered, and reinforced with a still-mysterious glue, these glass fibers stop cracks fast. The sponge also forms glass fibers at ambient temperatures and without any special steps. Man-made glass fibers require high temperatures — 2,000 degrees F — as well as chemical treatments in an expensive and energy-intensive "clean" lab.
