Blinc's Kiss Me Mascara. It literally cannot run/flake/etc.; I used it at Disney in the heat, and for my wedding ^_^ To remove it, I would take a shower, get my face nice and wet, and gently move my fingertips downwards on my (closed, obviously, hee!) eyes. They slide off in tubes. VERY, very cool.
Directly from website:
Blinc Kiss Me Mascara is the original tube-technology mascara. It's invented to form tiny water-resistant "tubes" around your lashes for maximum amplification and hold, rather than painting them like conventional mascaras. Once applied, the tubes bind to your lashes and cannot run, smudge, clump, or flake, even if you cry or rub your eyes.
This mascara adds both volume and length, to give you a radiant natural look that lasts all day. Neither water nor pressure alone will remove Kiss Me Mascara. Only the combination of lots of warm water and gentle pressure (no need for harsh makeup removers) will slide the tiny tubes effortlessly off your lashes into your hand. Upon removal, you will actually see the tiny tubes slide into your hand.
