Abstract
By direct imaging of scattered light, we observe shear-induced gelatio n in extremely dilute solutions of wormlike micelles. This gelation is followed by a fracture of the gel which produces extremely elastic ge l bands with recoverable strains of up to 5000%. The gelation and frac ture account for the unusual shear-thickening and elastic properties o f these solutions.
