I love the trick and the method. I would have given it 5 stars if it wasn't for the bag. The bag she
used on Penn and Teller was much larger.
The bag that came with the trick is too small and
not shaped properly to allow me (and I'd assume others) to easily perform the required moves.
To overcome this problem without having to buy material and make a larger bag, I use a large
pillow case instead and find that works well as long as I don't put the pillow case past my elbows.
Even with the bag issue, I would highly recommend this trick to others.
