Need to know before attempting this trick:
3 ball cascade - see tutorial 1
Bonus to know:
3 ball shower
441

Note: Step 1 and step 2 are not essential to this trick but they do help a lot, the trick's actual movements are all covered in steps 3 and 4 however, having to throw the props in different directions becomes difficult if you can't shower. (Hygene-wise too)

Step 1
Three ball shower thrown in a synchronous pattern.

Step 2
Opposite side of step 1.

Step 3
Throwing one ball up in hand "A" vertically and thowing the second ball from hand "B" to hand "A" in a synchronous pattern.

Step 4
Opposite side of step 3.

All Together
Now combine steps 3 and 4 so the pattern is continuous. Just do one and then the other before the vertical ball lands.

Thanks for watching.
