The silk cabby is an innocent looking wooden box having two doors that when opened, reveal an empty chamber with two large holes at opposite ends. It can be turned completely around proving it is empty. Now, three white silks are pushed one at a time in the box and each emerges a different color out the other side. These colored silks are then pulled through the box and emerge tied together. The box can be shown empty any time. Many other effects are performed with this classic and versatile box.
