Experiments were carried out to study the behavior of gas-liquid interface in a horizontal closed glass pipe which was installed in a free fall capsule in a drop shaft facility. Just after the pipe was put under the micro gravity, the liquid layer broke into a number of groups and formed liquid plugs with a nearly equal spacing. The average pitch of these liquid plugs varied with the liquid volume fraction and the pipe diameter. The measured value agreed well with the wavelength of fastest-growing disturbance on an annular liquid film obtained from the linear stability analysis.
