How NOT to secure a waterproof camera prior to jumping

Shot this with an old waterproof camera years ago on the American River in NorCal below Beacroft trail. Accidentally let go of it in the whitewater and it fell to the bottom of the river. By luck it flipped right-side up and some fish came to check it out. It also eventually ran out of data while filming so I trimmed it but it was on the bottom of the river for maybe 40 min or so and while rated for about 12 feet was clearly deeper. :(

It still worked for years after that but made "noises" when zooming
