In the video, a person is seen decorating a dessert with a green substance. The dessert appears to be a cake or pastry, and the person is using a piping bag to apply the green substance in a swirling motion on top of the dessert. The green substance is likely a type of frosting or glaze, and the person is wearing a white glove, indicating that they are a professional or taking care to maintain cleanliness. The background is blurred, but it seems to be a kitchen or a bakery setting.
