How to make an electrically detonated fireworks igniter that can be used to detonate waterproof fireworks underwater.
Step 1: Materials
- one christmas tree light (not LED)
- one paper match
- stone/ metalwork file
- hot glue gun
- duct tape
- waterproof firework (obviously)
Step 2: Saw off the very tip of the christmas tree light.
saw off the very end of the christmas tree light with the file, be very gentle as the light will break easily.
Step 3: Insert Match into light
cut off the very tip of the match, and put it gently inside the light; making sure it touches, but does not break the filament.
Step 4: Add firework
insert the fireworks fuse into the light, off to the side of the match. make sure the fuse is in good and tight. remember. the firework/ firecracker has to be waterproof too.
Step 5: Sealing the light
put a dab of hot glue inside the light, and around the fuse. make sure there are no air holes, or water could get in.
Step 6: Stripping and sealing the wires
you will need an ignition source, that provides at least 3 volts. i am using an old model rocket ingniter. strip off the ends of the wires, and put the ignition wires onto it. once the wires are connected, but aa strip of duct tape around them so that they are watertight too.
