In the magic trick, what was Lee trying to show his classmates?

The answer is that Lee was trying to demonstrate his ability to make something move without physical contact. This relates to the core principle of many magic tricks, where performers create the illusion of movement or action without any apparent cause, captivating the audience's attention. This aligns with the typical goals of a magic trick, which often involve demonstrating seemingly impossible feats that provoke wonder and curiosity.

By focusing on moving an object without touching it, Lee aimed to showcase a particularly impressive form of illusion that highlights the mysteriousness of magic. This also demonstrates his understanding of the principles behind such tricks, as they rely on sleight of hand, misdirection, or the use of specific props that create this illusion.

The other options, while related to performance skills, do not capture the specific act of demonstrating movement without contact, which is the essence of what Lee was trying to accomplish in his trick.
