with the water....don't believe the hype in the videos of kids filling their mouths with water and spraying it over the lip. this doesn't work that well and only effects a half inch or so deep of the snow. the lip doesn't hold up and crushes in, especially with skis and their small surface area. soak the lip by pouring water over the entire area, wait a minute, put some salt (rock salt) on it, wait another couple minutes and you should be ready. this all is in the idea that the temperature is below freezing.
hope this isn't a troll.
