The factory is a 3 ball trick where one hand juggles two balls (usually in columns) while the other hand does right-angled carries, dropping a ball into the one-handed pattern and taking another one out every few beats. The normal factory is an asymmetrical pattern that repeats every three beats:
- The right hand throws a ball straight up, while the left hand carries a ball up to the top of the pattern on the left side, synchronized with the ball on the right.
- The right hand throws another ball straight up, to the left of the last ball it threw, while the left hand carries the ball it's holding horizontally across the top of the pattern, crossing over to the right side of the pattern.
- The right hand throws another ball straight up, to the right of the last ball it threw, while the left hand (which should now be farther to the right than the right hand) drops the ball it's been holding down to be caught in the right hand, and then quickly moves back to the left side of the pattern to claw the ball that was thrown on beat 2.
Make sure your hand stops moving horizontally before you drop the ball, so it will fall straight down.

Variations[]
- Alternating factory: Do the same three beats described above, but alternate doing the right-handed version and the left-handed version.
- Reverse factory
- Relf's factory
- Cross-armed factory
- 2-beat factory (the pendulum):
- The right hand throws a ball straight up on the left side of the pattern, while the left hand carries the ball it's holding horizontally across the top of the pattern, crossing over to the right side of the pattern.
- The right hand throws another ball straight up, to the right of the last ball it threw, while the left hand (which is now farther to the right than the right hand) drops the ball it's been holding down to be caught in the right hand, and then quickly moves back to the left side of the pattern to claw the ball that was thrown on beat 1.
- 1-beat factory (the waterfall): The right hand throws a ball up to the left side of the pattern, while the left hand carries the ball it's holding horizontally across the top of the pattern, crossing over to the right side of the pattern, drops the ball down to be caught in the right hand, and then quickly moves back to the left side of the pattern to claw the ball that was thrown from the right hand. This is easiest when done in an asynch pattern (siteswap 3) with two distinct "beats": throw and carry, then drop and claw. The waterfall is not always done with claw catches.
