Extend: Now we are ready to remove the firework! Add all code just below what you just added.
- In LOGIC from drag Loop through List into the event. It should be indented once!
- Change value to p and my_list to particle_list.
- In GRAPHICS from drop Remove Sprite in the new loop. It should be indented twice!
- In .remove_sprite() command, change sprite to p. Click Run, Submit and Next to fix the trails.
