IF you can prove these are made of silk, I'll eat one of them.

The quality leevl is lackluster and the gimmick is really blatant. I wouldn't use this to fool a drunk, let alone a child.

If you want to perform this effect, get Dan Harlan's Packs Small Plays Big Show For Kids, and do "21st Century Silks".
The materials are reasonably priced, and the effect will look much better (execution is the same, there's just a different gimmick.

The gimmick here looks thrown together, and it looks overly bulky.

It works, so it gets 2 stars.
