Make your own mini grappling hook out of everyday office and household supplies, then let let loose on a top secret mission from Her Majesty's Secret Service.
This grappling hook design was built from the new book Mini Weapons of Mass Destruction 2. This book has over 30 types of weapons and gadgets which can all easily be built with office or household supplies, most of which I had on hand already! I chose to build a personal favourite, the grappling gun. I recently got my hands on a copy of this book, you can read my review here.
Enough talk, let's make a mini grappling hook!
Step 1: Tools + materials
Step 2: Hooks
Step 3: Launch barrel
Next, snip your rubber band and tape each end to the outside of the marker cap on opposite sides. Use plenty of tape to secure the rubber band in place. Lastly, wind a small amount of masking tape in the centre of the rubber band after it's been attached to the marker cap, this will act as the catch when you arm the grappling hook gun.
Step 4: Handle, stock and trigger
Using hot glue, stick a clothespin on top of the two pencils over the floss container. This clothespin will act as the trigger.
Finally, add the launch barrel previously assembled on top the taped-down pencils, on the opposite end from the handle with the rubber band draw facing the clothespin.
Step 5: Spool and line
Lastly, remove the ballpoint pen bottom and feed the loose end of the floss into the back of the pen and place the end cap back on, thereby sandwiching the floss into the back of the pen. If you're having trouble getting your floss to stay in the back of your pen try tying a few knots in the floss and then feeding the knots into the back of the pen.
Step 6: Fire away!
You're all done, time to test out your awesome grappling hook!
Pull back the elastic band and feed the catch into the clothespin. Your grappling hook gun is now armed. Carefully feed the ballpoint pen into the barrel and place the end right up against the clothespin, depress the clothespin to fire your grappling hook!
