Intro: Small Dart Gun
small simple dart gun powered by a flammable substance.
Step 1: Gather Your Supplies
peizo electric lighter ignitor
hot glue gun
Step 2: Put It Together
take the pen barrel and insert it into the highlighter front side put some hot glue were it was inserted then set up the ignitor by using some hot glue and glueing it to the side of the highlighter then set up a spark gap by poking 2 holes in the tube using your knife and inserting the wires close together.(the closer hte wires the hotter the spark is) now wrap the ignitor in duct tape so when you push the button it wont fall off.Now put hotglue were each of the 2 wires for the spark gap were inserted so there is no leaking of liquids.
well your done and all you have to do now is use a fuel source that works and a paperclip to jam the projectile down the barrel (just a suggestion use a needle and poke it through the barrel so when you put in the projectile it doesnt fall through)to anyone with suggestions to make this any better feel free to post
