Here's an analogy.

The spell for floating an object is Wingardium Leviosa. It usually takes an 11-year old a few days to become proficient at it.

Please give an estimate for a modification of this spell that will make the object lift, complete two vertical circles (720 degrees) and then go back to the starting point.
