Abstract: Special effects containers that include a special effects substance are provided in, for example, greeting cards, gift bags, photo albums, postcards. This substance may comprise particles (e.g., a glitter or confetti) and a liquid (e.g., water) such that when the special effects container is shaken, a visual effect is produced. One type of visual effect produced is similar to that of a snow globe. For example, pieces of a polymer confetti, each having the shape of a snowflake, may be included in a special effects container with a liquid. Such confetti may have a negative buoyancy with respect to the liquid such that after the special effects container is shaken, the pieces of confetti sink. The rate of descent/ascent of the container particles can be configured by changing the specific weight of the liquid or particles.

Abstract: The present invention provides visual effects in, for example, greeting cards, gift bags, photo albums, postcards. Visual effects are realized through special effects containers that include a special effects substance. This substance may comprise particles (e.g., a glitter or confetti) and a liquid (e.g., water) such that when the special effects container is shaken a visual effect is produced. One type of visual effect produced by the present invention is similar to the effect produced by a snow globe. For example, pieces of a polymer confetti, each having the shape of a snowflake, may be included in a special effects container that also houses a liquid. These pieces of confetti may have a negative buoyancy with respect to the liquid such that after the special effects container is shaken, the pieces of confetti sink. The rate of descent/ascent of the container particles can be configured by changing the specific weight of either the liquid or the container particles.
