In the video, a person is seen sitting on the floor with a large plastic bottle filled with water and beads. The person is holding a balloon and is using a lighter to heat the balloon. As the balloon heats up, it begins to expand and rise. The person continues to hold the balloon over the bottle, allowing it to expand further. The balloon is then removed from the bottle, and the person holds it up to the camera, showing off the now fully inflated balloon. The person's actions are deliberate and careful, ensuring that the balloon does not pop or burst. The video provides a clear view of the process of heating and inflating a balloon using a lighter.
