One more time.

A group of people in a backyard use a large wooden A-frame structure to launch a person in a swing high into the air, with the person swinging upward and then falling back down, while others watch and react; the scene cuts to a dark indoor setting where a person in a black high-top sneaker steps onto a surface, followed by a group of people in a dimly lit room, some sitting and others standing, as one person in a dark dress throws a large object into the air, causing a burst of white smoke or powder to erupt and scatter among the crowd.
