A Marked and Borrowed Quarter - Video Download (Excerpt of Klose-Up And Unpublished by Kenton Knepper)

From the DVD Klose-Up And Unpublished by Kenton Knepper comes an amazing routine whether you show a long balloon used for making balloon animals.  You borrow a coin, have it marked, and cause the coin to penetrate inside the balloon.   It looks absolutely amazing.
