Step 1: What You'll Need
- Rope (see notes below)
- Weights - I recommend steel ball bearings, but rocks and such would work.
- Duct tape (huzzah!)
For tools, I recommend:
- A Nice Sharp Knife (no, really, the sharper the knife the easier it will be to cut the rope later). I highly suggest something with a Wharncliffe (a.k.a. Sheepsfoot) blade for cutting rope, but any sharp blade is better than any dull blade, so use what you've got.
- A hot glue gun (not included in the picture. If you're not sure what this is, leave a comment)
- Optional: a flame-emitting device such as a candle or Bunsen burner
About the rope:
For the purposes of this instructable, I would recommend a homogenous, nylon rope. Nylon rope will be "fluffier", and is also more susceptible to melting, which is a beneficial factor when preventing fraying. The rope should have a similar diameter to the weights. Some cheaper rope will have some sort of alternative fiber running down the core (see image 01b, comparing the ropes).
Step 2: Taping Off the Rope
Cut a square of duct tape (see image, if you're confused by this step, but really...) and wrap it around the rope. Each piece of tape can form the heads of two darts. Alternatively, the tape can just act as a good binding for the end of your rope to keep it from fraying, once the darts have been cut off from the rope.
Step 3: Cut Off the Heads
Step 4: Add the Weights
You have two options for attaching the weights to the rope:
Option A: Melting and taping
This assumes that the rope you are using will melt before it will burn
- Using your heat source, get the tip of the rope reasonably soft (image 4a).
- Before the rope has cooled and hardened, press the weight against the tip of the rope (image 4b). This just ensures that the weight will fit snugly with the rope.
- Apply duct tape to the weight and rope. I would suggest leaving some overlap and cutting flaps for folding over, to secure the weight (images 4c, 4d and 4e).
Option B: Hot glue
- Apply a liberal-but-not-excessive dollop of hot glue to the end of the rope.
- Press the weight into the glue.
- Hold until cool (image 4f).
- Once the glue has cooled, you may still want to apply duct tape, to ensure a secure hold and because, well, it's duct tape: why wouldn't you want to apply it? But don't go overboard.
Step 5: Separate the Darts
Step 6: Fluff the Tails
Step 7: Secure the Tail
Step 8: Apply Force!
There are many modifications you could easily make which could make these darts more or less dangerous, such as:
- Apply an oogoo/Sugru coating to the head for padding
- Exchange the weights for something pointy such as nails or pieces of coat hanger wire
- Coat the tips in something flammable and ignite before throwing
Note that none of these modifications are advised or endorsed, but that has never really stopped anybody who regularly visits this site before.
Again, have fun and be careful.
