in this instructable I will show you how to make a Nerf Grappling Gun, that's kind-of like a Batman version. (Not necessarily.)
I apologize for any non-good lighting in my photos. anyways, lets get to building.
Step 1: The Materials
one Nerf gun (a pistol, with pull-back handle)
one #3 Lego rod
three Lego "cross-connectors"
one "headless" Nerf dart
one "Delta connector" (a tri-connector)
three Lego "insect legs" (is that what you call them???)
a large Lego cone (optional & not pictured)
Step 2: Putting Together the Hook
Step 3: The Hook
you need to take the other pieces and put them together as the pictures show
Step 4: The Final Product
then put it into the gun.
(i would recommend that you do a air restrictor mod to the pistol so you get a better range with the grappling hook, as it's heavy)
