Buzz Magnets™ (6pcs)
The "singing" Buzz Magnets™ also known as Mars Stones have a unique elliptical shape that creates a loud and strange "insect-like" noise when thrown into the air together. These highly polished and powerful magnets are great for teaching magnetism, are a great relaxing tool or paper weight. They can also be used for a science experiment or for tricks. They make a great gift. Each measures 2 inches long. 6 pieces included in a drawstring pouch.
