The High-Low Cascade
(unofficial name) is a variation of the three ball Cascade in which each
regular throw is paired with a simultaneous vertical toss from the other
hand. This short toss is quickly caught by the hand that threw it, resulting
in no net disruption of the overall Cascade pattern. This trick
is fairly simple to learn, with only the regular Cascade as a necessary
To begin learning the High-Low Cascade, start with one ball in each hand. Simultaneously make a high Cascade throw from your dominant hand and a low vertical toss from your non-dominant hand. If timed correctly, the tossed ball should be caught by your non-dominant hand as the other ball reaches its peak. When practicing it is best to exaggerate the height difference to make the timing easier.
As shown, practice this on both sides. Once you are very comfortable making these two throws in both hand configurations you will be ready to add in the third ball. Start with two balls in your dominant hand and one ball in your non-dominant. Make the same simultaneous throws you performed in the previous step but then, instead of simply waiting to catch the high ball, you will make another pair of simultaneous throws, this time making the high throw with the ball that was previously used for the short throw. This will clear space for your non-dominant hand to catch the high throw made by your dominant hand. The second high throw (made by your non-dominant hand) will then be caught by your dominant hand.
Practice this on both sides. You have just completed two cycles of the High-Low Cascade. Simply keep making pairs of of high and low throws to continue the pattern, as if juggling a tall Cascade.
