Firework Rocket
minecraft:firework_rocketA Firework Rocket is a craftable projectile that can be launched by hand, fired from a dispenser or crossbow, or used to boost elytra flight. Crafted with paper and gunpowder, it can carry up to seven firework stars to customize its explosion, color, and duration, dealing damage that scales with the number of stars attached.
FAQ
How do I use a firework rocket to boost elytra flight?
Use it while gliding to propel yourself forward at roughly 33.5 blocks per second, with the boost lasting as long as the rocket's flight duration.
Can firework rockets be fired from a crossbow?
Yes, they work as crossbow ammunition and only deal damage if they contain an explosion effect; a Multishot crossbow fires three at once.
What happens if a rocket has no firework star?
It will not explode on hitting a solid block and instead glides along the surface, though it can still damage entities if it has an explosion effect.
How many different fireworks can be made?
Combining colors, shapes, and effects allows for an astronomically large number of distinct fireworks, around 2×10^136 by the wiki's count.
