A Thunder Gourd is basically a drum made out of a gourd, with a spring attached to the drumhead. When the spring is shaken, it creates vibrations that are amplified through the drumhead into the gourd resembling sounds like a thunder storm; it is impressive!
If you have questions, please email me. They typically run anywhere from $45 to about $150 for the biggest size I carry, plus $10 for shipping. If there is a specific design that might interest you, let me know and I could probably come up with it.
This is a Native American Style Flute and Thunder-Gourd combo made from a single long handle dipper gourd. First one I've made but working on more.
