Such a gadget could only be invented by an illusionist. Adam Wilber has put in his hard work to invent Pyro fireshooter to add that spark in his performances. Adam Wilber took the inspiration for this device from the flamethrowers often used in his shows. But his idea was to provide his audience with a much more dangerous and breathtaking phenomenon. A magician releasing fireballs from his palm counts as one of them.
Pyro is basically a miniature model of the flashgun which uses paper treated with specific chemical and cotton. This combination burn instantaneously and is the driving component of this gadget. Wilber has specialized in his fieldwork of illusion where he wrote books about trick, produced his own video DVD sessions, the invention of Pyro is just the next step for him. Prior to the current working model, four prototypes were build and it took about two complete years to make this device efficient and secure for use.
To use Pyro all you have to do is wear it as a watch. Pyro has a wearable strap though which it can be worn and is quite compact in size. It is activated using a button which acts as a trigger for the device. By pushing the button the device releases fireballs. This button can be put in another hand or in your pocket depending on your feasibility. Since it has such a simple machinery and compact size it can also be used as a spy gadget. Women can also wear it as weapon for security but its reliability in stressful situations is compromised.
The wearable component derives its power from two AAA batteries and a separate battery source is required to power the trigger. To power the trigger a 2032 watch battery is used. The wearable component has four cavities that need to be loaded with combustible substance before the trigger is pressed. When the trigger button is pressed a signal is sent to the glowplug of wearable component which in turn ignites the cotton and paper, which shoots it out of the cavity creating the fireball effect. At a time one cavity releases the fireball and the device can be loaded again when all the four options are exhausted.
