Is it difficult?
Not the least bit. Full instructions are included with purchase, partly written by Chris Schuh of Team Ellusionist. No stone is left unturned-- learn everything you need to know quickly and easily. Any man can be a Superman-- all it takes is this effect (and a few hundred trips to the gym).
Do I need sleeves?
No, it can be done with or without sleeves.
Do I end clean?
It depends on the technique you choose to perform Superman. There is a method (as seen in the preview to the left) where clean up is INSTANT.
Can I borrow the coin?
YES. That's the power of SUPERMAN. Be sure to have it initialed too. It truly is the same coin that gets bent at your fingertips.
