I made it out of a few household objects, it launches Q-tips anywhere between 30-50ft.
Step 1: Supplies
1.Pen (all you will need from it is the plastic body for the barrel, so make sure you can fit a Q-tip inside of it)
2.Pill Bottle (the small kind that are like an inch in diameter)
3.Electrical or Duct tape
4. PVC Glue or some other type of glue that is very strong (i only used pvc glue becuase i found some in my garage)
5.A sparker- There are two possible sparkers you could use
1. I took a grill lighter and took it apart and just took out the butane tank and the long metal neck thing, so when it was done all i had was the body of the lighter with 2 wires sticking out of it ( there a picture of it on one of the next pages). - You will need 2 screws for this type of sparker
you can also use a grill sparker which would be easier
2. The other type of sparker you could use is a lantern sparker, i haven't actaully used one of these on something this small but i would guess it would work.
6.Drill with small bits ( obviously for putting the small holes in the pill bottle)
