Marden's Marvel is a three ball
pattern established by
Daniel Marden. It is essentially Rubenstein's Revenge
with an extra throw inserted during the flourish. This gives the trick an
aesthetic more similar to the Windmill, with its circling arm motions and
ball paths. If you are already very comfortable with Rubenstein's Revenge
then you might find this pattern very easy to grasp through simple
adaptation, but for this tutorial I will work from the ground up.
To begin learning Marden's Marvel, start with two balls in your dominant hand and one ball in your non-dominant. Cross your arms such that your dominant arm is underneath your non-dominant arm, then make a vertical throw from your dominant hand. After that throw is made you will begin to uncross and then recross your arms such that dominant hand is on top. As your dominant hand begins recrossing (after having uncrossed), the ball it previously threw should be beginning to descend. Make a throw from your dominant hand after it is about halfway finished recrossing, clearing space for that hand to claw catch the first ball. You will then make an under-the-arm throw from your non-dominant hand toward the non-dominant side of your body, clearing space for it to catch the second ball thrown from your dominant hand. Your dominant hand will then claw catch the ball just thrown from your non-dominant hand as it reaches its peak.
Practice this on both sides. For the next step you are going to make a throw from your dominant hand before it catches the last ball of the previous step. This throw should be roughly identical to the throw your dominant hand made while recrossing. You will then perform a vertical under-the-arm throw from your non-dominant hand along the dominant side of your body, clearing space for that hand to catch the ball just thrown from your dominant hand. This last throw should then be caught by your non-dominant hand.
As shown, practice this on both sides. Notice that the final throw of this step is a mirror image of the first throw. To run the full pattern simply repeat the the same throws and catches using the opposite hand configuration. Marden's Marvel is not all that difficult of a pattern, but when performed with speed it can impress and confound even an experienced juggler.
