Rhabdomancy is a word that means "divining with a rod." Rhabdomancy is when people use special sticks or rods to find things hidden in the ground, like water or treasure.
The way it works is, a person holds a special stick or rod in their hands and walks around. When they get near the thing they are looking for, the stick moves or twitches. This is like magic!
But really, it is just science. The stick is made of a special material, like metal or wood, and it is very sensitive. When the stick comes close to something that has water or metal hidden underground, it starts to move on its own.
It is important to note that not everyone believes in rhabdomancy, and some people think it is just a trick. However, some people have used rhabdomancy for a long time and believe it works.
