Potato Bazooka Igniter

[TorqueVR]

Hi Guys

I need some help. I want to make a mortar to fit my grandson's jeep trailer (see photo) from plastic pipe



This is the sort of thing I have in mind, and I'm OK with the basic components but I can't work out what he's used as an igniter/trigger. Any suggestions?

How about a piezo igniter as found on cigarette lighters and gas ovens?

For greater reliability, but at much greater expense, some form of trembler coil would put out a continuous stream of sparks.

Back in 1992, I visited the ex's parents near Moscow. By their cooker they had a thing about the size of a soldering iron that plugged into the mains and had two electrodes on the end. When a button was pressed, a continuous shower of sparks, a bit like arc welding, was produced between them. I don't recall any problems getting the hobs lit!

Section 5 firearm, prison etc

That said, we used the igniter off a gas bbq with hairspray.
Worked well.

Yep, some sort of glorified NERF gun might be a bit more child friendly - whatever is coming out of it needs to be something that won't do any damage 'cos you know that sooner or later it's going to be pointed at someone if a kid has it.

I'd just use a Nerf gun.

You can get some pretty good belt fed ones. Spray it up and job done.
