One ping pong ball for each firecracker you plan to make. Thick string, which will be used as the fuse. A sharp nail and a razor to make holes in the ping pong ball. Duct tape or another sturdy tape to patch up the hole. Fireworks, if they contain a star, will damage mobs and items in close vicinity. If you have a pair of elytra wings, fireworks will come in useful to propel you long distances. First, make a firework rocket with no star. If you want to go farther use more gunpowder. Hold the rocket in your hands.

Assemble a Homemade Firecracker

How To Make Homemade Fireworks Without Gunpowder Without

1. Make homemade firecrackers no longer than the length of one finger joint. (G36)

   Roll a strip of cardboard or paper around a pencil to make a hollow tube. Tape the paper to hold the shape in place and remove the pencil.

2. Cut the tube into 1″ or 2″ sections.
3. Tape the bottom of each tube to seal it.
4. Add a small amount of kitty litter (clay) to a tube and use the pencil to press it down to the bottom. Use the erase end to pack down the clay to make a plug.
5. Add black powder or nitrocellulose to the tube. Insert a piece of fuse and continue adding powder around it until you are near the top of the tube. Don’t be stingy with the fuse. You want to get it into the gunpowder and make sure there is enough exposed fuse outside the firecracker that you can light it and get away from it before the fuse burns down to the gunpowder.
6. You have a few options for sealing the tube. If you’re working with paper and plan to light the firecracker immediately, you can firmly twist the paper around the fuse to seal the firecracker. Another option is to top off the gunpowder with a small amount of kitty litter. Tape the top of the cylinder, leaving fuse exposed. Finally, you can just tape the top of the firecracker, leaving exposed fuse. Experiment to see which design works best for you.

Firecracker Safety Information

• Gunpowder or nitrocellulose are flammable and will explode if they are compressed when they burn. This, of course, if how firecrackers work! Make sure the materials only explode when you’re ready by keeping your work space away from heat and flame.
• It’s a firecracker, so it should be made by and lit by an adult.
