This project allows you to use electromagnetic levitation to suspend a globe of the world above a surface. The "globe" is actually a table tennis ball painted to look like a globe. Keeping it in place requires careful control of electrical current to an electromagnet. Therefore, this project uses an Arduino interface board that is programmed from your computer. The Arduino is a great platform for building this "anti-gravity machine."
