Ultimate Tak Ball is an indoor sport where the two teams of 4 players each attempt to deposit a giant inflatable soccer ball into a goal while the other team tries to stop them with tasers. The tasers are the kind that you might use to defend yourself from a mugger in a dark alley!
The taser devices emit a charge of three to five milliamps, sufficient to cause a localized muscle spasm but no permanent damage to any of the body’s vital organs.
