How to Do the 190 helix cut card trick
The 190 Helix cut is a pretty cool false cut that you can do with cards. When you cut the cards, the queen of hearts-which was there at the beginning-is somehow still on top after the cards seem to have been sufficiently cut. What you need to do is separate about ten cards from the top with your finger. Lock that in the opposite hand between the forefinger and thumb. Now put your ring finger down and flip the cards back. Do this and continue to rotate the stacks of cards so that the small pile with your queen ends up on top.
