Incredible footage of a helicopter going down way too fast
Great example of an important fact about perception: We don't directly perceive the size of objects; the perceptual system makes an educated "guess" based on preexisting knowledge, the size of nearby objects, etc.pic.twitter.com/BQzpvJ5AK1
Replying to @SteveStuWill
It's really interesting that I 100% saw this as a full sized helicopter that was going to crash the first time I watched this, but now that I know it's a toy I can't see it as a full sized helicopter again.
