Liquid data chain
A liquid data chain was a type of information device that came in liquid form.

In 2370, Quark helped the Klingon mercenary Yeto gain access to Deep Space 9 during a plasma storm in order to purchase a case of liquid data chains. The sale, however, was a ploy and the Klingon was actually part of a team hired by Verad to steal the  symbiont. Despite Quark's help, he was taken prisoner along with the rest of the station's senior staff. ()
