Carateristica, which translates into “fireworks,” is a new Italian term for a firecracker. The vehicle is made from a single gasoline-powered engine that produces the blast rather than charcoal or petrol. Although it may not appear to be, the carateristica actually consists of two separate vehicles. The first vehicle (the one with the engine and the nozzle attached) contains a spark plug and the second vehicle (the one without the spark plug and nozzle attached) contains a small explosive charge attached to a primer.
The vehicle with the spark plug and nozzle attached uses a double pool system, while the vehicle without the spark plug and nozzle uses a single pool system. The mechanism used to generate the blast is similar to a typical megaturn, using a percussion cup in the base and double cones in the top of the cup. When a series of balls are propelled by an electric motor through the cup, the firing pin forces these balls to split and become separated. The resulting explosion causes the entire cone assembly to collapse, creating a powerful force against which the balls can rebound. The carateristica is therefore able to produce a highly destructive stream of fiery sparks and sound.
In order to use the carateristica in a traditional manner, it is recommended that a group of people be transported to a location where the device is situated in such a way that there are no obstacles in its path. In this way, the explosion can be directed at the people around it who will then be forced to evacuate the area. In addition to this, some precautions must be taken to ensure that no civilians get injured in the blast. For instance, it is recommended that the carateristica be parked in a location away from any flammable objects, so that if such an object were to catch fire, the people inside the area would not be harmed. Also, it is important to ensure that the device’s’reload life’ is maintained high; otherwise the device might malfunction after sustaining a certain damage.
