Hive five is a reaction where an instant V spark hits a pair of beehives, which reform transparently. Paul Callahan originally discovered the reaction on December 24, 1998.

Periods with known compatible sparkers are 32, 41, 46, 64, 72, 73, 84, and 126. Herschel factory-based loop oscillators can be constructed for any period 63 and above, that generate a V spark capable of supporting the hive five reaction.

The hive five reaction creates a spark capable of supporting the bumper reaction, enabling engineered bumpers for periods 63 and above.

The leftmost bumper is supported by a spark from the p41 pi-heptomino hassler with "hive five" attachment, and two more bumpers are chained on the right (click above to open LifeViewer)
