SOUND BOTTLE
A sound recording/playback device using tilt control
The bottle has no button. All interactions are activated through the tilting angle of the bottle. When it is set straight, it will automatically start recording. When it is tilted, it will automatically start playing.
There are excessive sensors that were designed for additional features that were not implemented in this version of the bottle.
The tilting angle of the bottle determines how fast the recording plays. The bigger the angle, the faster and louder the sound plays. When the sound is almost over, it will slow down and simulate the feeling of running out of water.
