Do you have old floor tile you want to remove, but you dread digging and scraping it out of the goo? Just take a page out of NASA's book and think like they do when a "lift-off" is needed. Did you ever see a rocket on a launch pad? The smoke you saw drifting down is super-cold liquid nitrogen escaping. It blasts the space vehicle into orbit. Sometimes you can use the same thinking to remove old floor tile. Try putting a large piece of dry ice on a cookie sheet and placing it directly over the tile (or tiles). The intense cold and rapid cool-down often will cause the tile to pop free without scraping or messy hard work. It doesn't work every time, but when it does it's a sight to behold -- like the launch and lift-off of a rocket. When you have old floor tile you want to remove, load in the cold stuff and count down to lift-off. And that's the On The House tip for today.
