The boy is pouring the Jurassic Sand from his little bowl into a sieve that is set over a hole in Table Covering with Holes. He pours all the sand in and watches as it seems to disappear through the sieve. He dives back into an adjacent hole to scoop up some more sand. He scoops with his whole body. He pours the sand in the sieve a second time and watches it as the sand disappears again. His friend across the table is making sure the child pouring the sand really knows where it is going.
