Magnetism is one of the phenomena in physics whereby materials attract or repulse other materials. References to this mysterious phenomena dates back all the way to ancient Greece! In China, the ancient scientist Shen Kuo was the first to write about the magnetic needle compass and it’s ability to determine true north—by the 12th century, the Chinese were known to have used the lodestone compass for navigational purposes!! Now you can see the power of magnetism at work with this cool kit! Use the building blocks and track holders to create a cool cannonball effect with the ball bearings! Create an incredible chain reaction, and have fun watching momentum work! You can even try using different combinations to get different magnetic chain reactions! Illustrate the wonders of magnetism to your child in a new and creative way!!
