If you look closely in the new Minecraft 1.11.1 (that’s a lot of ones!) 16W50A snapshot changelog, you may notice that there’s a new change to firework rocketss. While ambiguous, it simply says “there is a new use for the fireworks, but remember to be careful when handling explosives”.
The gif above by SirBenet shows that the rockets can be extremely deadly. When launched at a player, the fireworks take away 8 hearts. It’s definitely enough to kill a Ghast!
Back when firework rockets were added to game in 2012, many wanted them to cause damage. They only had to wait just over 4 years!
SirBenet also discovered that fireworks will ‘stick’ to you until they explode if you’re wearing Elytra. You can effectively become a flying creeper!
Fireworks machine gun?
Another Reddit user has designed a firework rocket machine gun. This will be very useful in war, allowing you to pummel your enemies with rockets.
