2 Fans, 1 Paper Airplane


----------------

“Thrust is the force that is the opposite of drag. Thrust is the push that moves something forward. For an aircraft to keep moving forward, it must have more thrust than drag. A small airplane might get its thrust from a propeller. A larger airplane might get its thrust from jet engines. A glider does not have thrust. It can only fly until the drag causes it to slow down and land.” Source: NASA.

  1. That is too cool. It’s amazing what visually stunning things you can do by employing simple principles of science.

  4. Not so amazing. The airplane is riding in the dead spot in the center of the fan’s vortex. The same fan placed vertically would hold a beach ball in the air in the same way.

  7. Looks like a fake to me. The fans are not facing each other perpendicularly. If they were they’d be more ‘edgewise’.

  9. Last time I checked when two forces are opposite and equal (as is the case of thrust -> and drag <-) there is no acceleration. I think someone needs to study the basic laws of physics again…

  11. Watch the video again. Notice the setting on the first fan is on low, and the setting on the second fan is on high. I tried this at home and got similar results, only mine didn’t sit in the sweet spot for as long as their’s did. If it doesn’t work, fold another plane. You need the right plane with the right fans the right distances away, but if you play with the variables for a while, it does work.
