Here is a cup that would fit beautifully at your parties and nighttime events. Flicker glassware recognizes your hand and lights up when you touch it. The light automatically turns off when you let go of your cup. Flicker cups are charged using solar cells that are mounted at the bottom of the cup. Just turn your cup upside down to start charging it. 4 hours of charging should be enough for Flicker to last you a couple of months.
Flicker is good looking and convenient to use. It is also dishwasher safe. It is available in various colors (white, green,yellow,red and blue). You can catch these on Indiegogo.
