Talk about killing two birds with one stone. Caffeine in your toothbrush! 

Colgate has revealed plans for a toothbrush with a built-in caffeine patch to deliver the morning coffee as you brush.

The patent application from the Colgate-Palmolive Company revealed technology that would allow chemicals to be embedded into the heads of standard toothbrushes and slowly released during use.

The firm showed off plans for everything from mint- and apple-flavored patches to a caffeine patch to wake up the weary in the morning. Each patch would last around three months.  

Would you try this for your caffeine fix instead of coffee?
