Ah that's a shame.
Being half asleep myself then seeing a big shadow of a question mark in my bathtub seemed bizzare for a moment until it twigged that it must be a hair.
Isn't it amazing the blobs & patterns that are created by the oil & the light though!.
I turned off the torch & shot a load of flash photos in the dark, as it was to awkward trying to hold the torch in one hand, phone in the other, while hitting the hair at the right angle with the torch, then hitting the shutter button with my tongue lol.. just joking, but yeah I didn't fancy dropping my phone in the bath while trying to press the shutter button with the same hand
