Fireworks to go lets you spawn fireworks and fountains to your liking. Just tap anywhere on the screen to shoot a firework rocket to that location. If you tap for a bit longer the fireworks will spawn extra crackle. If you tap near the bottom of the screen you will spawn fizzing fountains. If you tap for a bit longer the fountains will be higher and larger. You can spawn as many rockets and fountains as you please and your phone can handle.
