How to make a Firework Battery Tonight, we build a firework battery! The first thing we need to do is to make an underground redstone clock. Make sure the dispenser points into the dirt next to it, not up or down. You can decide the rate of fire by changing the delay of the repeaters. At night, set the sensor to trigger when dark to stop the dispenser from firing. In daytime, make set the sensor trigger when lit to stop the dispenser. Now for the rockets! You can make whatever rockets you like the most. The dispenser can hold up to 9 different rockets which it cycles through at random. I’m making the classic and cheap red/green/purple bursts that everyone buys! If you’re unsure of how to make the rockets, you can watch my tutorial by clicking HERE. The battery will only work around midnight or midday. To turn it on, I simply have to right-click it! Hurray! Have fun playing around with the rate of fire and rocket types! Happy new year!
