Ship in a bottle is a period16 oscillator found by Bill Gosper on August 7, 1994.^{[1]} If the ship is removed while not being interacted with, it becomes a bottle. If a pond is placed inside instead, it becomes pond in a bottle.^{[2]}
A related pattern, pond in a bottle uses the pond as a rock (click above to open LifeViewer) 
A 49glider synthesis of this oscillator was found by Jeremy Tan on April 18, 2019.^{[3]} A reduction to 48 gliders was found later by constructing a 22bit constellation^{[4]} with eight gliders.^{[5]} In April 2023, the same 22bit constellation was constructed with 7 gliders, reducing the glider cost of the ship in a bottle to 47 gliders.^{[6]} A 45glider synthesis was found by KtT in November 2023.^{[7]}^{[8]}
