p10 domino fountain is a period-10 oscillator found by David Raucci on June 14, 2022 using his oscillator search program. It is the first usable period-10 domino sparker. This one is a fountain, as it has a clear row between the domino and the rest of the oscillator.

Immediately after its discovery, two period-40 oscillators and a related p50 oscillator were completed, as shown in the gallery below, as was the variant shown in the infobox, a reduction by AlbertArmStain.
