Abstract: An apparatus to record a user's reaction on a recordable medium. The apparatus includes a container having a top portion hingedly fixed to a bottom portion. An interior section of the container houses a recording device in communication with the bottom portion. At such time as the top portion and bottom portion are separated beyond a defined distance, the recording device becomes activated to record still image, audio, and/or video of a person within range of the recording device.

Abstract: The invention is a method and apparatus for generating vortex rings in a fluid medium. The apparatus is immersed in a body of water and includes first and second bodies. Gas is fed into a concave surface of the first body via a conduit from a finite or infinite supply source. As gas is supplied to the concave surface a single unitary bubble is formed therein. When the volume of the gas in the concave surface has attained the volume of the concave surface, the unitary bubble travels as a single unit to an exit aperture. A vacuum is formed between the two bodies when the unitary bubble enters the exit aperture. This vacuum functions to pull the entire unitary bubble through the aperture. Following departure from the exit aperture, a toroidal shaped bubble is formed.
