I believe the TurboFlare 360 is also advertised to float, though I probably won't throw mine in the {vulgar term for feces}bowl to verify that...better use the sink instead. /ubbthreads/images/graemlins/wink.gif
BRB...checking that - with a SINK of course...ok, it does float in water, with the top of the bezel with the LEDs above the waterline so diffraction will not be an issue.
