Word puzzle: Open your hands, throw the watermelon, pinch two fingers, pick up the sesame seeds.

Open both hands, (8)

Throw the watermelon, (4)

Pinch two fingers, (7)

Pick up the sesame seeds. (10)

Personally, I think the eight characters look like two hands open, the four characters look like the "西" character for watermelon minus the upper strokes, and pinching two fingers is what we Chinese do when we draw the number seven. Gestures, I’m not sure about the last one, just pick it up, right? So guess ten.
