I have a humanoid character with wings, made possible by a little fictional magic, but I'm trying to keep it as scientifically correct as I can.
All right, so she has wings, but walking through busy streets, or around wingless humanoids at all for that matter is going to do much more than raise eyebrows. She needs to be able to effectively blend in, and that means her wings have to become invisible to the naked eye.
The wings are feathered and bird-like with a 14 foot wingspan. They can fold into her back.
I'd like to note that doors or any other physical object would not be a problem if her wings could not manipulate or be manipulated by matter when invisible.
I want the wings to be:
Invisible to the naked eye
undetectable by easily accessible scanners (infrared, etc..) (preferred but not essential)
If the wings can't manipulate or be manioulated by matter in any way shape or form while invisible, that's even better.
unable to be used in any fashion when invisible
able to be made visible and usable at will. If it takes a few seconds for this to occur that's fine. Any more than a minute or two and it's getting a bit iffy.
possible naturally without the use of technology (if possible)
Is this possible, and if so please explain, or does it have it to be explained with more pixie dust to work?
Hopefully the edit cleared things up a little bit.
