It takes longer to talk about this than it does to do it.
A lampara is a fuel/flash shell. It is among the easiest to make but the construction can be ruined easily because of the fuel bottle leaking or breaking. Since it contains flash and fuel oil, it is as dangerous as a large salute. Be careful with these and only attempt the construction after you have mastered other shell building techniques.
I get my lampare cans from Wal-Mart's Photo Shop
but any 3 1/2" outside diameter cardboard tube
I use vending machine Pepsi bottles for the Lampare bottles.
My lampare cans are a bit short so I extend them
Glue 1/2 a can on another and tape
Put a solid end cap on the bottom. Use another
end cap when you paste the shell in
Put some dried wood chips (litter from a pet
shop - dry it in an oven or drying cabinet) in the
bottom of the case to cushion the bottle
Fill the bottles with kerosene
Seal the bottles with caulk. Cheap caulk works fine.
Using a gloved hand, press the caulk around the
bottle to make a tight joint.
Pour about 100 grams of flash around the bottle. Fuse
another end cap and glue on top. Spike vertically only.
Paste in with four layers of 50-70 pound paper. I used a
double fuse on this one (to get around the close fit of
the bottle to the top of the end cap).
This shell will weigh about 2.5 lbs. I use 3 ounces of 2FA
for lift. There is a 3 second delay on the shell.
See regular shell construction articles for how to spike and
finish the shell off.
Do not use more than 100 grams of flash on a bottle this size. Too much flash will ruin the effect - all your audience will see is a big bang and no fuel burning.
