I consider two identical quantum particles in two boxes. We can split each box and thereby the wavefunction of each particle into two parts. When two half boxes are interchanged and combined with the other halves, where are the two particles? I solve this problem for two identical bosons and for two identical fermions. The solution can be used to define a measurement that yields some information about the relative phase between the two parts of a split wavefunction.
