Infrared and also red? HOW AMAZING!
You know how you'd give directions to a buddy going past the old high school hangouts? "Drive by the corner that used to have the burger joint, the one that closed in 2005, but used to be there back in the day." Infrared is the same way. You can't see it, but in your heart you know it's always there. Also, it'll cook your food pretty well.
