unorthodox methods to make yourself sneeze

[Absolute1]

I know that there are some ways that are diagnosed, like a photic sneeze reflex, but what is the most unconventional way to make yourself sneeze that works without fail? For me it has to be rubbing directly above or on the bridge of my nose. Just stirs up an immediate tickle that ALWAYS leads to a satisfying sneeze.

Covid testing ! LOL (okay, it's not that unorthodox, sorry but here you go)
