A thumper is a device used in a variety of magic tricks, typically with mentalism acts. It consists of small vibrating device that is triggered by a remote radio transmitter by a confederate in the audience. Practically any such device can be used, from custom equipment to everyday pagers.
Mentalism is a performing art in which its practitioners, known as mentalists, appear to demonstrate highly developed mental or intuitive abilities. Performances may appear to include hypnosis, telepathy, clairvoyance, divination, precognition, psychokinesis, mediumship, mind control, memory feats, deduction, and rapid mathematics. Mentalists are sometimes categorized as psychic entertainers, although that category also contains non-mentalist performers such as psychic readers and bizzarists.
Radio is the technology of using radio waves to carry information, such as sound and images, by systematically modulating properties of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form.
A pager is a wireless telecommunications device that receives and displays alphanumeric or voice messages. One-way pagers can only receive messages, while response pagers and two-way pagers can also acknowledge, reply to, and originate messages using an internal transmitter.
In its most simple form, the confederate simply triggers the thumper at a given time. A classic example is to hide an object under a mug or cup, which the magician then discovers by slowly moving their hand over the cups and waiting for the thump. More complex forms can use codes.
A shill, also called a plant or a stooge, is a person who publicly helps or gives credibility to a person or organization without disclosing that they have a close relationship with the person or organization. Shills can carry out their operations in the areas of media, journalism, marketing, politics, confidence games, or other business areas. A shill may also act to discredit opponents or critics of the person or organization in which they have a vested interest through character assassination or other means.
In system programming, an interrupt is a signal to the processor emitted by hardware or software indicating an event that needs immediate attention. An interrupt alerts the processor to a high-priority condition requiring the interruption of the current code the processor is executing. The processor responds by suspending its current activities, saving its state, and executing a function called an interrupt handler to deal with the event. This interruption is temporary, and, after the interrupt handler finishes, the processor resumes normal activities. There are two types of interrupts: hardware interrupts and software interrupts (softirqs).
A thyristor is a solid-state semiconductor device with four layers of alternating P- and N-type materials. It acts exclusively as a bistable switch, conducting when the gate receives a current trigger, and continuing to conduct until the voltage across the device is reversed biased, or until the voltage is removed. A three-lead thyristor is designed to control the larger current of the Anode to Cathode path by controlling that current with the smaller current of its other lead, known as its Gate. In contrast, a two-lead thyristor is designed to switch on if the potential difference between its leads is sufficiently large.
A booby trap is a device or setup that is intended to kill, harm, or surprise a person or animal, unknowingly triggered by the presence or actions of the victim. As the word trap implies, they sometimes have some form of bait designed to lure the victim towards it. At other times, the trap is set to act upon trespassers that violate personal or restricted areas. The device can be triggered when the victim performs some type of everyday action, e.g., opening a door, picking something up, or switching something on. They can also be triggered by vehicles driving along a road, as in the case of victim-operated improvised explosive devices (IEDs).
A spark gap consists of an arrangement of two conducting electrodes separated by a gap usually filled with a gas such as air, designed to allow an electric spark to pass between the conductors. When the potential difference between the conductors exceeds the breakdown voltage of the gas within the gap, a spark forms, ionizing the gas and drastically reducing its electrical resistance. An electric current then flows until the path of ionized gas is broken or the current reduces below a minimum value called the "holding current". This usually happens when the voltage drops, but in some cases occurs when the heated gas rises, stretching out and then breaking the filament of ionized gas. Usually, the action of ionizing the gas is violent and disruptive, often leading to sound, light and heat.
An incantation is a magical formula intended to trigger a magical effect on a person or objects. The formula can be spoken, sung or chanted. An incantation can also be performed during ceremonial rituals or prayers. Other words synonymous with incantation is spells, charms or to bewitch. In the world of magic, the incantations are said to be performed by wizards, witches and fairies.
An alert dialog box is a special dialog box that is displayed in a graphical user interface when something unexpected occurred that requires immediate user action.
Thumper or The Thumper may refer to:
A spar torpedo is a weapon consisting of a bomb placed at the end of a long pole, or spar, and attached to a boat. The weapon is used by running the end of the spar into the enemy ship. Spar torpedoes were often equipped with a barbed spear at the end, so it would stick to wooden hulls. A fuse could then be used to detonate it.
The magic SysRq key is a key combination understood by the Linux kernel, which allows the user to perform various low-level commands regardless of the system's state. It is often used to recover from freezes, or to reboot a computer without corrupting the filesystem. Its effect is similar to the computer's hardware reset button but with many more options and much more control.

"Ain't No Magic Mountain High Enough" is the thirteenth episode of the second season of the American mystery television series Veronica Mars, and the thirty-fifth episode overall. Written by Diane Ruggiero and directed by Guy Bee, the episode premiered on UPN on February 8, 2006.
Psionics, in tabletop role-playing games, is a broad category of fantastic abilities originating from the mind, similar to the psychic abilities that some people claim in reality.
Carroll Wayne Harris was an American professional football player who was a linebacker for the Calgary Stampeders of the Canadian Football League (CFL) from 1961 through 1972. His son, Wayne Harris, Jr., coaches football and also played for the Stampeders of the CFL.
The Hitachi Magic Wand is an electrical, AC-powered wand vibrator, originally manufactured for relieving tension and relaxing sore muscles, but most famous for its use as a sex toy. Japanese company Hitachi listed the device for business in the United States in 1968. Sex educator Betty Dodson popularized its use as a vibrator and masturbation aid for women during the sex-positive movement in the late 1960s. It functions effectively as a clitoral vibrator and is able to bring many women to orgasm. The wand is 12 inches (30 cm) long and weighs 1.2 pounds (540 g) with stimulation provided by its rubberized 2.5-inch (64 mm) head.
Close-up magic is magic performed in an intimate setting usually no more than ten feet from one's audience and is usually performed while sitting at a table.
The reveal is a plot device in narrative structure, and is the exposure to the reader or audience of a previously unseen key character or element of plot or of the performance.
