Present contribution addresses some aspects of the behavior of a bubble chain composed of bubbles with Re in the range (based on the terminal velocity of single bubble). Bubble chains were created using bubble generator with oscillating needle or acoustic bubble generator. These devices enable to create bubble chains with different initial spacing and bubble diameter. Air bubbles were rising in various liquids as ultrapure water, silicon oils and ethanol.

Two interaction scenarios was observed - a) coalescence in line; b) chain disarrangement. Transition between this scenarios occurs depends on initial separation distance also.
