Abstract: The invention relates to a high-temperature stable, one-part, aqueous tooth bleaching composition for contacting a tooth surface. The composition comprises a bleaching agent comprising a high level of a aqueous hydrogen peroxide. The bleaching agent is derived from multiple components within the composition and comprises at least about 15% by weight of the total composition weight. The Composition also comprises a bleaching agent stabilizer comprising from about 0.01% to about 1.00% by weight of the total composition weight.

Abstract: A crab trap is provided having an open configuration prior to trapping a crab and into which a crab can crawl to retrieve bait placed therein, the trap also having a closed configuration for trapping a crab therein. The trap has a generally rectangular frame assembly comprising a base frame having two hollow bottom side connecting tubes and two hollow bottom end connecting tubes connected at their corners by corner elbow connectors. A plurality of hollow vertical corner posts is inserted in the corner elbow connectors and is three dimensionally perpendicular to the rectangular frame. The vertical corner posts each have a longitudinal opening extending from the lower end of the vertical corner post to the approximate center point of the vertical corner post along the length of the vertical corner post. The bottom side connecting tubes, bottom end connecting tubes and vertical corner posts all contain a plurality of openings to permit water to flow through.
