Spring Catch

To be sincere I didn't like it, first of all it is a dribble not a spring and second, that little pause you do before "catching the card" and the pause later, gives out the method. anyway props for being creative.
 
You're right.

Was to be done with a spring, but I only had a
hand. :D
Use an assistant.

Thank you.
 
I had this idea a while back and after playing around with it for a while, could not get it looking much better than you! It is hard to do well, although in theory you would think it's pretty easy!
