I'm going to attempt to spend all night in the bath full of water with my blue pyjamas on and the light off.

Should be fun in the dark with my soaking wet pyjamas and the water pushing and sticking the collar of my blue pyjama jacket against my neck and chin.

Should be able to see the shine on my soaked pyjamas in the moonlight through the window, certainly can see the buttons on my wet pyjama jacket.
