Floating Rooted Trees
There is a place in Mexico that lets you drive under these two floating, living trees. How are they alive, you ask? The roots that you see at the bottom here aren't really the roots of the tree, this is merely an illusion.
Just Like in the Movies
The root system of the tree actually grows into the hollow concrete barriers that are holding the trees up, since the concealed part of the tree is the only part that gets water or any nutrients. This gives off the illusion that these trees are growing out of thin air, but they're merely suspended in a sort of growth purgatory.
