Abstract: A cap, a magic kit, and methods for performing a magic trick are described. The cap can include a circular top end having an interior surface and an exterior surface, a side wall extending radially from the circular top end, an open bottom end, a thread on a side wall interior surface, a groove proximal the interior surface of the circular top end and a portion of the side wall, and a marker. The cap may be used to perform a magic trick where the groove retains a coin in the cap when the cap is flipped over.

Abstract: A magic kit and methods of use thereof are described. The magic kit may include three pairs of shoelaces, each shoelace in each pair having a magnetic end and an aglet end, and at least one shoelace having two aglet ends. The magic kit may be used to perform a magic trick where the shoelaces are removably coupled and uncoupled from each other.

Abstract: A magic trick apparatus and methods of use is described. The magic trick apparatus may include a half sphere having a rounded side and a flat surface with a coin attached to the flat surface of the half sphere. The magic trick apparatus may further include a band and a ridge on the rounded side and a hole extending into the half sphere. The magic trick apparatus may be used to “transform” a coin into a lollipop.

Abstract: A two-card sleeve apparatus is described. The two-card sleeve apparatus may include a first transparent layer, an opaque layer, and a second transparent layer. The two-card sleeve apparatus may be used to safely store or display two or more trading cards.

Abstract: A scale apparatus is described. The scale apparatus may include a housing sized to fit within a playing card tuck box; a pressure plate operable to measure a weight of a plurality of objects; a wireless transmitter; and a microcontroller in communication with the pressure plate and the wireless transmitter. The microcontroller may be configured to: continuously measure the weight on the pressure plate; when the weight holds steady for a sequence of measurements, transmit a first weight measurement via the wireless transmitter; measure a change in the weight; and when the change in the weight is steady, transmit a second weight measurement via the wireless transmitter.

Abstract: A magic kit and methods of use thereof are described. The magic kit may include a first handheld object and a second handheld object that appear to be identical but have different weights. The magic kit may be used to perform a magic trick where the second handheld object appears to levitate using an elastic band.

Abstract: A magic kit and methods of use thereof is described. The magic kit may have a set of cards, each card comprising a plurality of holes and an order marker. The plurality of holes on each card are arranged in a different order. When the set of cards are stacked on top of each other in a specific order, using the order markers as guides, only some of the holes of all the cards in the set align to form a pattern.
