Here’s a new product in the shot glass market called the Envious Ounce. Its a shot glass that lights up when tapped on a hard surface. The light stays on for 6 seconds and then shuts off. The shot glass is made of high quality glass, is frosted to enhance the effect and has a replaceable battery. Under normal use the battery usually lasts more than 2 years at a time. Definitely for someone who needs to look cool in the dark. Going for $9.99 a pop
