“You want to hold it in your hand, with the flat
side down. Wrap the side of the rock with your index
finger, like this. Then sling it. It’s best to toss sidearm.
You don’t want to aim it down at the lake too much.
You want the rock to be whizzing just inches from the
top of the lake. And, as you let go of the rock, you
want to snap your wrist so the rock starts spinning .”
