Tumbler is an alarm clock that is shaped like a vase. It can be placed as an interior accessory on your bedroom nightstand. The alarm clock is made of acrylics and works like a skipjack. The signal is interrupted whilst pushing down the body. When released it swings back and the signal starts again. A balance sensor inside detects the particular position and controls the signal. Pushing two buttons on the body at the same time only deactivates the alarm.
