silencers on spudguns

hi again im just wondering as im making plans to upgrade my recently made spudgun if silencers are legal on spudguns. it would make sense so because spudguns arent considered guns,but im just wondering because it may still be illegal.

lol thats why alcohol was out in the first place. also i could use a perfume thing but i dont really want to use a spray and pray like that. i was thinking of more of using a syringe with check valves with a tiny nozzle.

lol no problem. plus....

as wikipedia quotes:
"It is unsuited as a fuel in alcohol stoves because of the relatively low vapor pressure of isopropyl alcohol, and because the water content will vaporize to steam creating excessive pressure in the stove."

im digging the excessive pressure part :D

cool. plus i have some personal experience in burning alcohol(im a retired pyromaniac ) and alcohol evaporates fairly well in the right settings. we did a test in school and it evaporated rather fast. plus thx for the answers guys, i have a good feeling my next cannon will run on alcohol. 8)

i can understand that as it enters the chamber id need to atomize it, i was guessing with maybe a chamber fan, but is that idea viable? that my big question. :lol:

is alcohol a useable fuel?

hi, i was just wondering, is alcohol a usable fuel? i shot my first spud gun today, it was using static guard and as i was filling the chamber with the spray, i wondered, "it would be so much easier to use a liquid!" so it is possible? or is it too weak/strong?

hey totally random right here, but is it really possible to use a marx generator and if so could all the little sparks gaps be used in the chamber? even though they'd be closer it would make a fairly amazing ignition.

its a basic one, but i plan on making a more advanced one soon.
also, for a spark couldnt you just hook up a capacitor to a little transformer if you were going to make a spark strip or so?

the best shape i know of is called the sears hackbody, which looks like a cigar with pointed tips on each end. its best for areas around the super sonic speeds but i think its should be ok. somthing simpler though, golfballs
