Magnetoid 60x18mm Pair

Two super-srong, special oblong magnets that are amazing. Made from Haematite, they are smooth and safe to handle. Spin them on a smooth surface and as they attract each other, listen to them chirp!! A new, fun way to demonstrate magnetic force and other principles. Why do they chirp? Where is North and South? What happens as they collide? How can two little magnets be so ridiculously entertaining? Play with magnetoids for just few minutes and find out. Before you know it you will be entranced by their spinning, chirping, wobbling ways. Upon releasing the Magnetoids they immediately perform a magic, magnetic ballet of attraction and repulsion, clashing, spinning and making an amazing ear-catching, insectoid, chirping sound in the process (....called a ‘glissando’,....meaning rapid sliding up or down the musical scale.”) Each size 17 x 59mm.
