In the video, a person is seen mixing a large bowl of dough. The dough is white and appears to be of a thick consistency. The person is wearing a black shirt and is using their hands to mix the dough. They then proceed to add green food coloring to the dough, which is in the form of a bottle with a white cap. The person squeezes the bottle and adds the green food coloring to the dough. They then mix the dough again to ensure that the food coloring is evenly distributed throughout the dough.
