The Hat Coil is a classic production item, which was a favorite with magicians a few years ago. Unfortunately, the non availability of the coils specifically made for this purpose makes this an item rarely seen today.
The original production used to be from an empty magician's hat, which is how the item got its name. The magician produced hundreds of yards of ribbon from an empty hat. The result was a mountain of ribbon, several times the size of the hat. Finally this could be used as a cover for a much larger production, for example picking up the ribbon, and under cover producing live stock or several umbrellas from a body load.
The ribbon is really a paper strip, and one hat coil can be used for only one performance. However the modest cost is well justified for the very big impact of the production.
You get a compact coil, about 1 inch thick and 5 inch in diameter, that when produced forms a mountain of paper ribbon. Although traditionally produced from a hat, you could also make the production from any production prop, such as a Square Circle or Tip Over Box, or any item where you can conceal the coil in the load chamber. It is ideal for production from a Tambourine Ring, where an endless ribbon seems to cascade for the tissue capped empty rings.
