This summer my oldest boy discovered the joys of river rope swings.
The first time he tried it, he fell off into the river at the nadir, when the force is strongest.
The next few tries bore the same result.
Then I told him to grip the rope higher and tighter… that if he could hang on through the bottom of the arch, he’d be able to swing back up and drop off at the top.
Sure enough, on the next swing he held on for dear life through the bottom and earned himself a nice drop down into the river.
