The World's Loudest Party Popper - The Most Portable Film Cannister Cannon

Step 2 Making the Cannon.

It may be pure chance, but every sparker I have had out of a lighter has been slightly longer than the diameter of a film cannister. That is the secret to this version's portability. That, and the fact that this version is made upside-down.

Other versions fire the cannister, this one fires the lid.

Near the bottom of the cannister, cut a small hole that is just large enough to fit the sparker's button through.

Bend the wire of the sparker over towards the larger contact and make sure it works - press the button and watch for the spark.

Slot the sparker through the hole from the inside of the cannister. If your fingers are even slightly on the chubby side, you may find it easier to use a pair of long-nosed pliers or a pair of forceps to do this. Try not to move the wire too much. Check that the wire is still in the right place to strike a spark.

There you go, you've finished - don't add any glue until you have checked the cannon works.

where do you get the sparker from and how

[Kiteman]

As it says in step one, the sparker is from an old cigarette lighter - I just broke the lighter to get it out.

i put a hole on the bottom, which surprisingly works as well...

[Kiteman]

What is the hole in the bottom for? Did you use a larger sparker than I did?

[cosmicmariorick]

no, i just used it as another path for the spark
