Abstract
We prove that the involution on the boundary $\Sigma$ of the Akbulut cork relating blown up elliptic surfaces to completely decomposable manifolds acts non-trivially on the Floer homology of $\Sigma$. We also show that $\Sigma$ provides an example of an irreducible manifold with non-zero boundary operator in its Floer chain complex.
