Miracle Dowsing Rod by Tenyo Magic Co t-280

This intriguing magic trick revolves around the mysterious theme of dowsing rods. Using two L-shaped metal rods, you will be able to locate a hidden coin, and a selected card.  No skill required.

Dowsing is an ancient divination method that attempts to locate hidden ground water and buried metallic ore. Practitioners of dowsing hold two L-shaped metal rods in their hands, gripping the short ends. The rods remain parallel to each other as the dowser walks around. When the dowser reaches an area where metallic ore is located, the two rods respond by moving in a mysterious way. This trick imitates this uncanny phenomenon in a visual and fun demonstration.
