Introduction: A Cheap Way to Make and Reuse Fire Cracker
Just need a bicycle valve, a nail, a match. We've got a fire_cracker.
Step 1: Cut Short a Nail to Get a Flat End.
Find a nail to fit the valve hole. Use grinder or something to cut it.
Step 2: Remove the Core in Middle of Valve
Using small Plier to cut it.
Step 3: Put a Match Into Valve Hole.
Maybe, compress it gently with a done-cut-nail. To seal the gap between body of valve and match powder.
Step 4: As the Image Above.
Use nail, attach it in.
Step 5: Compress to Make Explosion.
Use gravity or a heavy object, something make a huge force on top of the nail.
Step 6: Modification.
You could learn from this to make blank bullet , even for real gun -> fire cracker gun, making a long line of it, like Chinese Fire Cracker Sequence. Drop hundreds of it by using drone (Arduno => randomness dropping), like a bomber airplane.I learned and played it from a friend of mind in middle school. I don't know this invention from whose. Don't see anyone show thing like this in here. So i do it. It's a saving and fun.
