It's easy and inexpensive to make firecrackers yourself. This is a great pyrotechnics project, perfect for do-it-yourself types or persons who can't find firecrackers where they live.

2. Make a Sparkler

Sparklers are a type of firework that produces a shower of glittery sparks, but does not explode.

Sparklers are small hand-held fireworks that don't explode. They are among the safest and easiest fireworks to make yourself.

3. Fireworks in a Glass

This is a project that involves making red and blue food coloring 'fireworks' in a glass of water. It's a project that is safe and easy enough for younger kids to do, though adults will probably get a kick out of it too.

4. Make Black Snakes

Black snakes or glow worms are a basic non-explosive type of firework.
Anne Helmenstine
Black snakes are another type of firework that doesn't explode. Once you light these pyrotechnic devices they push out columns of black 'snakes'. This is an easy and safe fireworks project.

5. Classic Smoke Bomb

This is a fun project that only requires a couple of ingredients. When you light the smoke bomb, you'll get lots of white smoke, plus violet flames.

6. Safe Smoke Bomb

Most smoke bombs produce white smoke.
Anne Helmenstine
This is the non-cook version of the smoke bomb recipe. Since the ingredients don't need to be heated, you don't need to worry about spilling some on the stove and setting off your smoke alarm.

7. Colored Smoke Recipes

Colored smoke bombs work by dispersing dye into the air.
Anne Helmenstine
Colored smoke is easy to make, but you will almost certainly need to order the dye used to make the color from a pyrotechnic hobby shop. The color is produced by vaporizing the dye, not by burning it.

8. Fountain Firework

You can make a fountain firework using the homemade smoke bomb recipe.
Anne Helmenstine
You can adapt the homemade smoke bomb recipe to make a long-lasting fountain firework that shoots purple flames, plus a lot of smoke.

9. Homemade Fuses

This is an example of a finished homemade fireworks fuse.
Anne Helmenstine
Fuses are handy to have around for firecrackers and smoke bombs. These fuses use common household materials.

10. Patriotic Density Column

This red, white and blue density column is easy to make and uses common household materials.
Anne Helmenstine
You can layer red, white, and blue liquids according to their density. This project is easy and educational.
