I started this project, based on the plans at halloweenpropmaster.com. The difference is that I wired the skeleton's joints together inside, rather than gluing them, like he did. Anyway, I know that the prop is fairly effective since I have already had cars slowing down on my street to check it out!
Okay, it's my first instructible, so bear with me a bit.
Step 1: Start with a cheapo blow mold skeleton ...
I bought this at one of the Halloween super stores that pop up every year, so I probably paid way more than I should have. If you wait until after Oct 31st, you can probably find these for cheap cheap!
It is a simple, 5 foot tall, blow mold skeleton, made from cheap plastic and popped together by inserting a little tab into a hole in the next bone. The problem is that the joints don't bend well, and they pop out really easy.
Step 2: Sewing the joints together...
I poked a hole in the skeleton's hand and threaded some picture hanging wire through the hand and out the tab. I then inserted it through the other bones until I had about 2 or 3 feet hanging out of the shoulder end of the humerous (top bone in the arm).
And then I tied it off around the hand.
