A container assembly for encouraging a consumers to make initial and continually purchases of a consumer product by allowing entry into a game of chance with the purchase of the consumer product, comprising:

• a container for holding a fluid with a first density (D1) at a first pressure (P1) with a breakable seal;
• a game piece with a given buoyancy including game information for entry into the game, the game piece being placed within the fluid inside the container;
• and
• a first security measure associated with the game piece preventing viewing of the game information;
• wherein when the seal of the container is broken, the first pressure (P1) of the fluid changes to a second pressure (P2), and thereby causing a change in the buoyancy of the game piece to indicate whether the game piece is eligible into a game of chance.
