The human cannonball act is a performance in which a person who acts as the "cannonball" is ejected from a cylinder that has been specially designed to resemble a cannon. The human cannonball lands on a horizontal net or inflated bag placed at the landing point, as predicted by physics. Outdoor performances may aim at a body of water.

History

Rossa Matilda Richter ("Zazel") with her cannon in 1877.

The first "human" cannonball, launched in 1877 at the

tightrope
act.

In the 1920s,

World record

There is a claim that the current world record for the longest human cannonball flight is 193 ft 8.8 in (59.05 m),[3] established by David "The Bullet" Smith Jr. on the set of Lo Show dei Record, in Milan, Italy, on March 10, 2011. The distance was measured from the mouth of the cannon to the farthest point reached on the net. Smith was launched by an 8 m (26' 3") long cannon. It was estimated that he traveled at a speed of 120 km/h (74.6 mph), reaching a maximum altitude of 23 m (75' 6").

There is, however, a contradictory claim that Smith's father, David "Cannonball" Smith Sr., set a record of 200 ft 4 in (61.06 m),

The Steele County Free Fair, in Owatonna, Minnesota
. It is estimated that Smith Sr. traveled at over 70 miles per hour (110 km/h) during the flight.

Cannon

The impetus in the cannon is provided either by a spring or jet of compressed air. This makes the device work more like a catapult, where the cylinder propelling the human stops at the mouth of the cannon.[5] Some cannons utilize nitrocellulose, specifically the dinitrate ester, cellulose dinitrate (pyroxylin).

In a circus performance, gunpowder may be used to provide visual and auditory effects unrelated to the launching mechanism. Fireworks and smoke may also be used to increase the visual effect.

The largest retailer of these human cannons is located in Greensburg, Pennsylvania. This supplier provides approximately 80% of all human cannon catapults.[citation needed]

Risk

More than 30 human cannonballs have died during the performance of this stunt. Among the latest was that which occurred in Kent, United Kingdom on April 25, 2011, where a human cannonball died as a result of the failure of the safety net.[6] Landing is considered to be the most dangerous aspect of the act.[5]

Special forces

The human cannonball principle is the subject of a patent application by the US

Defense Advanced Research Projects Agency, whereby a rail-guided chair driven by compressed air is brought to a sudden stop, propelling the special forces member, police officer or firefighter onto the roof of a tall building.[7][8]
