- From a one quarter tag formation: In the wave do a Step Thru then Pass Thru the outside two to do a Partner Hinge and then arm turn half. New centers make a right hand star and turn it one quarter. Those who can left arm turn 3/4 and the others move up to the nearest end of parallel waves. Finishes in parallel waves.
NOTE: The name "Chain Reaction" was sometimes given to the old figure called Illegitimate Chain (see section on Special Movements).
