So is it a prop or is it a costume? That’s the question I was left with after watching the tutorial on the Anti-Gravity Machine that Brick in the Yard Mold Supply created. However you decide to categorize it, there is no question that it is completely awesome. It’s an incredibly intricate build that was definitely worth the effort. While an anti-gravity machine may not fit in a haunt (or be comfortable to wear at a Halloween party for that matter), the concept behind it could certainly be implemented and is worthy of at least a cursory look.
