Firework

A Firework is an event-only item in Survival 303.

Overview
Fireworks were released on December 30, 2012, presumably to celebrate the upcoming new year. They were a limited edition item which has been removed after the holiday. Fireworks may be lit after being placed by clicking on them. They will rise into the sky and explode in a colorful blast, although the explosion is purely aesthetic and cannot harm people or structures. There are three different kinds, although you get them randomly. One sprinkles "sparks" into the air, another flies into the air and explodes randomly, while another explodes in a beautiful circle.They may also be used a signal flare(e.g. a warning for war, a help signal,)
 * They now become available every 4th Of July (Per 2013)
