How to create the effect of fireworks pictures blooming in the air in PPT and make this effect play circularly?

I just tried it, and it went something like this:

1. The beginning of fireworks:

First insert the graphic to be moved (just a bright circle)

Custom Animation-Draw Path-Draw Custom Path (Draw Curve from Bottom to Top)-Set the speed and repetition number in the edit box on the right.

2. The tail of fireworks (which line)

Insert the same curve as the circular path-the animation is set to "Erase, the direction is from bottom to top"-repeat and set the speed.

compound

Check the position of the circle and the tail and move it.
