As for figuring out how he did it, whats the point? Can people not wait two days to find out from the guy himself?
Course not. The whole fun in magic is trying to work out how it's performed. He won't necessarily give the truth away on Friday.
Why wait 2 days if not build anticipation by allowing time for speculation? Why give that snowflake teaser away? He did this intentionally so people could enjoy themselves trying to figure out the puzzle for themselves.
