Animation of Fast Moving Projectiles with Smoke

A graphic animation depicts projectiles moving from left to right. The projectiles each have a center of bright orange and yellow. Behind each projectile is a cloud of white that appears to be smoke. The animation starts with only one projectile, then increases to two, then three, then four, and finally six. The smoke plumes get thicker, filling the frame. The animation ends with the smoke almost completely blocking the black background.
