This child has harvested some suds on his spoon. He tries to deposit in his green container, but the suds stick to the spoon and do not fall. He uses his other hand to scrape some of the suds off the spoon. Those suds stick to his hand. He then starts to hit the spoon onto the lip of the container in hopes of dislodging the suds from the spoon. He doesn't seem to get much off. He sets the spoon down and picks up a sponge. Then he takes the hand that still has the suds and presses it lightly to the sponge. Voila! Some of the suds comes out on the sponge. He grabs the sponge with both hands to squeeze it over the container. When you look at his hands when he is done squeezing, you can see that completes the transfer of suds into the container.
