Can an alchemist prepare extracts and bombs while spider climbing via the spell?

Had this come up and wanted to know.

Thanks!

Why not?

[Delrik]

The spell description states that both hands have to be free to climb but says nothing about stationary PCs. In 3.5 you had to keep both feet and one hand on the surface.

Well, an alchemist can have up to four arms. A couple of pitons and rope make it possible.

Your answer intrigues me sir!
