We present Giant Metrewave Radio Telescope (GMRT) H I 21 cm observations of two of the most metal deficient galaxies known, viz., SBS~0335-052E and W. They form a strongly interacting pair of galaxies. We present their H I maps at various angular resolutions. A diffuse H I bridge and extended tidal tails dominate the H I morphology and kinematics at low resolutions. Higher resolution maps show that even inner disks of both galaxies are disturbed. The large-scale velocity field is dominated by the gradient along the tidal tails. At high resolutions however, one can see a velocity gradient along the disk of SBS~0335-052W which traces the original rotational motion of the disk. HST images of SBS~0335-052E show an ionized superbubble expanding to north-west of its central super star clusters. The extensions of H I, in the region of superbubble, are aligned in the same direction. There is higher column density H I gas on the south-east edge of superbubble. The superbubble is expanding into a region of relatively low H I column density, produced by the ongoing tidal interaction.
