Incredible magic- right in front of their very eyes!
Place three borrowed ordinary quarters between the panels of the frame, so that the quarters can be seen through the holes in the top of the lid. Cover the coins with an ordinary borrowed piece of paper. Take an ordinary borrowed pencil- and push the pencil through the hole in one of the holes- right through the paper and the quarter! Repeat it twice more. And the grand finale- open the frame to reveal that the piece of paper now has holes poked through it, but the quarters are unharmed!
How did the pencil pass through the quarters without making a hole?? It's magic!
