Cutting a dark pet nail was once just a guessing game. Quick-See eliminates the guesswork by revealing the location of the quick, the vascular portion of the nail. When cut into, the quick bleeds and the animal feels pain. Quick-See strips are made of flexible vinyl coated with color-changing ink. The color change shows you the proper place to clip a dark pet nail. Thus far, Quick-See has been tested on dogs and rabbits.
They work in the same fashion as the mood ring and hypercolor shirt. When heated to a specified temperature, the ink loses it's color. Quick-See strips are set to change color over the live portion of the nail (the warm portion) while remaining dark purple over the dead portion of the nail (lower surface temperature).
Veterinary student Brent Crutchfield was frustrated with the number of times she witnessed veterinary specialists cut an animal's nail too short, resulting in pain and mess. So she set her mind to coming up with a solution to the problem of the invisible quick....
A year later in May, 2006, Quick-See was chosen as one of 25 semi-finalists in the History Channel's Modern Marvels Invention Contest out of over 4300 entries! It was the overwhelming public favorite (over 82%) according to the voting kiosk travelling with the Inventor's Hall of Fame Exhibit across the US.
