This post was lost in the Crocapocalypse – I’m reposting it with its original date.
We were at the beach today, trying to catch waves in a pool we’d made.
You can move a lot of sand trying to get the water to come – dig a big, wide channel – and never get a drop if it doesn’t go far enough towards the water, and each part isn’t deeper than the part before.
Build a small channel instead, a narrow channel, and deep, to where the water is. When the wave comes, the sea will do the work for you.
It’ll cut you a Grand Canyon.
