Because of its mass.
Gravity
Well, let's see. If I have a paper clip on a table and a magnet in my hand, and I slowly pass the magnet over the paper clip, the magnet in my hand is pulling the paper clip up with magnetism. If my magnet is close enough to the paper clip, the paper clip will jump up to the magnet ... even though the whole Earth is pulling it down with gravity.
The paper clip was not discovered. It was invented.
The paper clip clings to the the magnet
Becuase this tiny paper copter has a very low terminal velocity. The force of gravity on the paper copter is very small, so it does not have to fall that fast to reach an equal amount of air resistance. The force of gravity is equal to the force of air resistance on the copter while falling very slowly, so it cannot accelerate any more, making it fall slowly.
