When you are ready to launch, hold the cups between your thumb and index finger with the first digit of your finger inside the loop of the bands. Nex...
Step 3: Here's the wind-up, and the pitch!
Wind the bands around the middle of the cup using medium tightness. Winding it too tight will cause the cups to collapse. I recommend winding over the cups and coming out underneath. This method gives me a better launch, but feel free to experiment.
