Bounce juggling is juggling by bouncing objects (usually balls) off of a hard surface (usually the floor). Some bouncing tricks can also be done with rings and clubs. Bounce jugglers sometimes use portable surfaces to juggle on, since not all floors are suitable for bounce juggling. Objects can also be bounced off of surfaces tilted at different angles such as walls.
Since a dropped ball never bounces all the way back up to the height it was dropped from, maintaining a bounce juggling pattern requires the balls to be either lifted up with the hand after catching so they can be dropped from the same height every time, or thrown down at the floor to make them bounce higher than they would if they were just dropped. Juggling by lifting the bouncing balls is called a lift bounce, and juggling by throwing them at the floor is called a force bounce. In a lift bounce, the balls are caught on the outside and dropped down through the inside of the pattern so that the throws from the right hand and the throws from the left hand cross paths on the way down. In a force bounce, the balls are caught on the inside of the pattern and thrown down on the outside so that they cross paths on the way up.
Bounce juggling can be easier than toss juggling because the balls don't have to be thrown high, but numbers jugglers have been able to flash and qualify more balls in toss juggling than bounce juggling, and most of the world records for solo bounce juggling are lower than the equivalent records for toss juggling. Even numbers of balls are usually bounce juggled in a wimpy pattern rather than a fountain.
In some bounce juggling patterns, the balls bounce more than once before they are caught, but in the IJA Numbers competitions and in the official world records tracked by the Bounce Page, each ball thrown must bounce exactly one time before being caught. Since a stable pattern can be maintained by simply pushing the balls slightly to redirect them, without actually gripping them, any touch of a ball with a hand is considered a catch in bounce juggling, as long as no catches have been missed yet.
