| Hematite Zingers Made of genuine polished hematite, a semi-precious, naturally occurring stone, also known as iron stone. Because of the special elliptical shape when they are in pairs, the magnets are in a precarious state of balance. Separate them and toss gently together and they produce a strange whirring, chirping, and buzzing sound as they snap together many times a second before stabilizing again. Zingers make a fantastic gift for any young scientist - but be sure to get an extra pair for yourself! | ||||||
