I rember seeing a differant Blaine trick like the first video and rember against my Master Magician friend if he knew it, he knows all the tricks, but what the trick is is a coat of wax over the card that makes a person run thier hand over it when against the glass, i think (not forsure) that the signing the name *ink* must be why that card sticks to the glass. The second video (with blaine) is just high-dollar elastic *obviously the jewlery store was in on it* In case you dont believe in magic
