Light-up Rug That lights up each step!!!

It's 11:00 pm, and you just came home from a long night out. You have to go up stairs, brush your teeth, change into your pjs, and climb into bed without waking your children. Well you don't have to worry because now there is the light up rug, which will light up with each step you take. The light that the rug emits is very soft, and it will light up in response to your weight. Other light-up paraphenilia, use photoluminescence, for glow-in-the-dark toys, and chemoluminescence, which involves light producing chemical reactions, like light sticks. The light-up rung, however, uses an electric field to generate light. To read more about this light generating rung, go to http://www.livescience.com/technology/080325-rug-lights.html.
