Sound bubbles: Their collapse induces mechanical stress that can be transmitted to a target single bond by means of mechanosensitive polymers attached to the two sides of a benzocyclobutene. As surprising as it may be, ultrasound guides molecules into forbidden pathways by promoting the formation of only one isomer regardless of the starting benzocyclobutene.
