Auto Change Mirror Tube by Mr. Magic - Trick

Here's a magical way to change several objects into different objects! Show a beautiful, cylindrical tube to be empty. Place several silk scarves of different colors inside the tube. Close the lid so nothing can get in or out of the tube. BAM! When the lid is opened, the scarves are now tied together! Or, they might form one large streamer instead! Your imagination will figure out many ways to use this great utility device. It's magic!

Silks not included.
