The wave slack is a fairly easy slack trick, created by Joshua Yee.
- Start with a breakway.
- Go into a trapeze.
- Pinch the trapeze with your freehand, and underslack using your throwhand.
- Swing the slack all the way around and spin the yoyo also, alternating the slack, and the yoyo.
- Keep the motion going by catching and releasing the string you were pinching.
- Land a trapeze, and catch the yoyo.
