Glowing Liqour Pour Spout

This LED lit pour spout for your liquor is more than just a flashlight on top of a bottle. It uses the same physics as a fiber optic cable. The total internal reflection of the light in a fluid with a higher refractive index than air will keep the light inside of the liquor lighting up the curving stream and the liquid in the cup rather than lighting up the table. They make a great gift for anyone with a bar. Chances are they don’t already have one, and amazon has them cheap enough that you can afford to give away a bottle of liquor with it.
