In the video, a person is seen holding a blue slime mold over a yellow surface. The person then places the mold on the surface and presses it down, causing the slime to ooze out. The person then picks up the mold and squeezes it, causing the slime to stretch and change shape. The person repeats this process several times, with the slime changing colors from blue to pink and then to purple. The person's nails are painted green, and the slime appears to be thick and sticky.
