Will a paperclip or a binder clip fall faster on a paper helicopter?

A paperclip will generally fall faster than a binder clip when attached to a paper helicopter. This is because the binder clip is bulkier and has a larger surface area, which increases air resistance and slows its descent. The paperclip, being smaller and more streamlined, experiences less drag, allowing it to fall more quickly. However, the specific design of the paper helicopter and the weight of each clip can also influence the outcome.
