silicone as propellant

Post questions and info about combustion (flammable vapor) powered launchers here. This includes discussion about fuels, ratios, ignition systems and anything else relevant to launchers powered by igniting things like hairspray or propane.

I swear I searched the boards 3 times and didn't see this listed.

I was trying anything that said "extremely flammable"

Silicon spray was at hand.
side by side with starter fluid it fired everytime, and I didn't get crazy venting out the air in the chamber...
I made a louder pop too.

I figured it doesn't leave carbon dioxide like starting fluid does.
Or as much.
Plus it lubes the barrel at the same time...
A short 1 second burst was all I needed.

Anyone else use this before?

I bet that is very expensive.

It's a little costly, but it workes decentally. We used to use that in our getto guns here at school. One thing is it leaves a residue all ovber any thing that it burns near, so watch out for that.

Well strangley, I had a slight mishap with some silicone.
I sprayed a bit too much, trying to figure out how wet the mix can be.
When it didn't fire I opened the cap and was checking to see if the spark gap got bumped somehow.

I thought it vented enough, but appearantly it didn't.
I was careful enough not to stick my face to close when I clicked the ignitor, but a flame ball still managed to waft it's way out of the tube.
I didn't have eyebrows anyway, but the smell of burnt hair was amuzing.
Will most likely never do that again....

Ahahah! Boomer did that in his basement with his Blue Flame Clone. It went something like:

Brian: "I'm going to dry fire it."
Gort: "Uhh, well, your parents wont slay you?"
Brian: "Nah." *dumps propane meter forgetting that the first valve was still on*
Gort: "Hah, dumbass. Don't click that - "
Brian to himself (or so I assume): "Eh, I'll just vent it out and press the ignitor at the same time..."
Fire: "FLOOF!"
Gort: "Whah! I told you not to... Cap it up dammit!"
Brian: "Ahh! Cool! Ahh!"
Gort: "Dumbass..."

Ha! Suckers! I got by not going to initiation day...

I have had jets of flame from my ignitor holes on my mini steel gun burn the living [excrement] outta my wrist though...

Even though I've got <B>three</B> propane meters now, I still experiment for my first combustion, (over and under 1" barrel), with aerosols. I have some of this in the washing room. I'll try that real quick...

Don't worry, everyone goes through initiation.

Me: Dad, it didn't go off.
Dad: Don't do tha-.
Me: "Opens chamber and clicks button, looking at an angle." *WOOOOF*
Dad: Don't!
Me: That was cool!
Dad: You no longer have 2 eyebrows, your left one is gone.

Yeah, I ended up burning off my left eyebrow since it was at an angle. Dad ended up shaving the other one off in my sleep to piss me off and to make it look better.

On topic, silicone spray is about 5 bucks for 100 Ml of it.

Still testing some more.

Silicone spray is a lubricant? Hows the residue post firing when compared to starter fluid?

Note to everyone: Hope no ones lost eyebrows more than once!
