Abstract: A variable cutting diameter arrowhead includes a first blade, a second blade, and a ferrule, where the first blade and the second blade have a stowed position and a deployed position. The first blade and the second blade may be pivotally attached to the ferrule. In addition, a resilient member may be within a ferrule cavity, where the resilient member applies a force to a blade locking member that engages the first blade and the second blade to retain the blades in a stowed position. When the blades are in a deployed position, the distance between a distal end of the first blade and an outer surface of the ferrule is greater than the distance between the distal end of the first blade and the outer surface of the ferrule is in the stowed position.

Abstract: An action toy employs a vacuum chamber and vacuum pressure to propel projectiles inward to collide with materials or objects or structures inside the sealed vacuum chamber. Users are entertained by observing high-speed demolition and wrecking action. Air-tight containment of the chamber is required to create a vacuum, ensuring user safety and mess-free operation while providing close-up viewing and video capture from outside the chamber. Users can experiment with a wide variety of high-speed collisions, watch the results in slow-motion replay, and share replay clips with others using a smartphone. The toy can be used to create art works by blasting materials onto a canvas.
