In the video, a person is seen holding a handful of water beads. The beads are of various colors, including red, blue, green, and yellow. The person then proceeds to place the beads in a container filled with water. The beads are then agitated in the water, causing them to expand and take on a spherical shape. The person then picks up a single bead and holds it up to the camera, allowing for a closer look at the bead's expanded form. The bead appears to be made of a gel-like material that expands when in contact with water. The video provides a clear demonstration of how the beads can be used to create a visually appealing and tactile sensory experience.
