In the video, a person is holding a test tube filled with a red liquid. The liquid is bubbling at the top, indicating that it is being heated. The person is using a lighter to heat the liquid, causing the bubbles to form and rise to the surface. The test tube is made of glass and has measurement markings on it. The person's hands are visible, but their face is not shown in the video. The background is blurred, but it appears to be a laboratory setting.
