Answer:
As light as a feather, but you canβt hold it for ten minutes.
When Iβm metal or wood, I help you get home. When Iβm flesh and Iβm blood, In the darkness I roam.
When liquid splashes me, none seeps through. When I am moved a lot, liquid I spew. When I am hit, color I change. And color, I come in quite a range. What I cover is very complex, and I am very easy to flex.
By Moon or by Sun, I shall be found. Yet I am undone, if there's no light around.
I bind it and it walks. I loose it and it stops.
I can only be played on a windy day
