Buzz Magnets™ (6pcs)
Storus® Buzz Magnets™ are "singing" magnets. They are also known as Mars Stones. They 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 magic tricks. They make a great gift. Each measures 2 inches long. 6 pieces included in a velvet drawstring pouch.
