You don’t necessarily need a special occasion to have a shot. But keeping track of the amount of liquor you are consuming is important. The Shot Time Smart Shot Glass can help. It calculates the amount of liquor you have consumed over time. It keeps track of your shots until you reset it. Every time you pour a shot, Shot Time Glass will calculate the exact weight. Once drank, the glass recalculates the weight and does all the work.
The Shot Time Glass has a battery that should last you for a few months. It keeps track of the amount of liquor you are consuming so you don’t have to. You can support it on Kickstarter.
