The video shows a close-up of a sparkler burning against a dark background. The sparkler is emitting bright, sparkling light in all directions, creating a dynamic and festive display. The sparks fly outward from the tip of the sparkler, which is glowing intensely with a yellow-orange flame. The overall effect is visually striking and celebratory.
A sparkler is ignited, and it begins to burn, producing bright yellow sparks that scatter in various directions. The flame at the top of the sparkler grows larger and more intense, causing more sparks to fly outwards. As the sparkler continues to burn, the intensity of the sparks increases, creating a more vibrant display. The burning process progresses further down the sparkler, with the sparks becoming denser and more numerous. The sparkler maintains its burning state, with the sparks radiating outwards in all directions, creating a dazzling visual effect.
