Bring STEM learning to life in front of their very eyes! Create your own ferrofluid with this ferromagnetic powder kit. A great gift for kids who want to see experiments in action. Create the ferrofluid following the instructions and then watch the reaction as you move the magnets up and down the sides of the test tube, move them close to the tube and then far away and see the nanomagnets wave around as if being pulled by invisible strings. Ferrofluid is a liquid that has become magnetized, and it’s easily made thanks to this Ferromagnetic powder and water. Mix together, shake and then use the magnet to collect your ferrofluid in the test tube.
