| An overlay of three images at successive points during the
force-induced chemical change. The strands represent
polymer molecules attached to the mechanophore. The blue
image is the start of the reaction. Elongation of the polymer
caused by flow places tension on the mechanophore. The
yellow image represents the end of the reaction. The green
gradient in the background represents the velocity of the
solvent molecules rushing past the polymer (the darker the
color, the faster the solvent velocity).
