Abstract:
1. An apparatus, comprising: a container defining a reservoir with a variable interior volume, the container being configured to be selectively buoyant in a liquid based on a size of the variable interior volume of the reservoir, the container defining a hole, the reservoir being in communication with the hole; an actuator configured to receive a first user input from a user and configured to select the buoyancy; a timer disposed within the container; an audio system coupled to the timer and having a speaker in audio communication with the exterior of the container, the audio system configured to selectively produce an audible output for a user-specified time period with a volume that increases as the user-specified time period nears expiration, the audio system configured to discontinue the audible output when a second user input is received, the audible output having a user-selectable frequency; a sensor disposed within the reservoir defined by the container, the sensor being configured to determine an amount of liquid received within the reservoir; and a pump coupled to the sensor, the pump configured to expel or intake liquid based on a signal from the sensor.
