Quite some time ago (almost a year, it seems) there was a thread about whistling in the shower…a much more productive past time than, say, whistling in the dark (..whistling in the dark). The problem with this is of course that, on most whistles, the water closes up the tone holes. A quick, easy, and harmless solution is to rub a wee bit of olive oil on the front of the whistle, thereby preventing moisture build-up in the tone holes. Works like a charm. 
This, I think, is likely the most relaxing way to whistle.
(By the way, if you didn’t get the whistling in the dark joke, you should discover the joy of ‘They Might be Giants.’)
Until the hot water runs out. 
DISCLAMER: I have never tried whistling in the shower, so any comment I make on it should not be taken as fact and may be dead wrong. Still, I do not hesitate to comment.
I’m not sure but, playing with your whistle and olive oil in the shower seems somehow, how shall I put it delicately, a bit off-color. Not that there’s anything wrong with that. 
Are we talking wooden whistles here, or tin? I don’t think I’d want my wooden-fippled tin Clarke getting wet…
i think tin whistles, i wouldnt bring a wood one in the shower. but i have tried that and i live in apartments, and the neighbors bang on the wall and complain on me. so i am usually stuck playin outside because everywhere i go in my place people dont like to hear me play 
whistle.
I wonder if a low whistle would work better (bigger holes etc.)?
What kind of acoustics would a shower have?
hmmmmm, whistles fault or the whistlers? 
hehe
lol, well i pretty much live in a ghetto apartments, and the people who live there. hate any kind of irish, country, classical, or rock music. but im sure my playing has part do do with it too 
I haven’t tried it, but a Schultz Water Weasel seems to be the best choice for this. PVC and big tone holes - and a very nice whistle.
Gallant:
I think you should stop playing with yourself in the shower.
Nyuk.
PS. Thanks for the set-up.
i will use the olive oil suggestion. i regularly play whistles and flutes while floating in my pool and on canoe trips and while floating in the lake. you’re right, the water makes the holes not work and even when i move my fingers, the notes don’t change unless i shake off the excess water.
lots of people will be too chicken to try this. that’s ok. they just need to evolve.
Olive oil is a gift from Mt. Olympus.
