In the video, a person is seen using a clear glass as a base for a decorative piece. They start by placing a rubber band around the glass, then proceed to attach twigs to the rubber band. The twigs are arranged in a circular pattern, giving the appearance of a tree or bush. The person then adds small flowers to the arrangement, giving it a more natural and aesthetic look. The final product is a beautiful and unique decorative piece that can be used as a centerpiece or a conversation starter.
