The ad copy is accurate; no threads, magnets, no glue. That said, the method is unreliable and given to failure under a number of circumstances.

While I admire the creativity at play here, I will frankly resort to using a thread to achieve more predicable results. I will give the creator a few points for the handling of the box to prevent discovery of the gimmick.

The quality of the sound is poor, the background music at times almost over powering the creator's explanation.

I bought this one 3 days ago use my other account.
And when i saw the explanation, what the f#ck you are a genious man in this world!!!
I mean why the hell i never thought this idea, it's so simple but powerfull.
Imagine you can leave magnet, thread, elastic and you can do it without preparation.
But the reason i give just 4 stars because yeah the sound over the explanation little bit mash but that's not a big deal because even without the sound i get everything from the creator.
Over all, i recomend this one to you if you want to do haunted effect without traditional element like thread or magnet.
