Is this gif possible to happen?
or is fake?

>> No.5930057

posible.

>> No.5930058

got two fans and a piece of paper? do an experiment. :)

>> No.5930059

use a string

>> No.5930060

It's definitely fake.

Whether it could happen is a more interesting question.

>> No.5930064

there's no left ventilator (see pic)
invisible string ties object to the right ventilator

how do you know that crease isn't in the sky?

Don't talk about it. They'll know we know

I'd assume the air pushed by the fans in the middle would create turbulence which would push the plane away.

As far as I know paper planes can't fly, only glide, so it can't happen.

>> No.5930495

A properly designed paper airplane could produce lift and stay at a fixed altitude, yes. But the problem would be that there would be no force to counter the right-to-left force from the airflow. So, while the plane might stay "up" for a very short time, it would immediately just go to the left and get sucked into the fan.

It's possible, but it could just be a loop of an eight of a second of video.

More that it's very difficult. The fans being used would make it difficult to balance. Like balancing a jug carton on a corner, or using a blow dryer to hold a ping ball afloat.

Given the dark shade in the plane, it looks like they also balanced the plane as well. As the momentum is the air instead of the plane, this allows the plane to act as a pivot joint, and basically self-adjusts to the position of least resistance. Treat the plane as a static armature, and the air as the object force is acting on.
