Query: Good concept and good magents

The set has many experiments which can be used to teach children various properties of magnets. The instructions for creating levitating train are not very clear. It is difficult for the children to join everything together and make it work. It takes multiple attempts to perfect it and make it work the way it should.Overall, it is a worthwhile set to teach the properties of magnets through fun experiments.
