Web-gun
From Tardis Wiki, the free Doctor Who reference
The web-guns were weapons created by the Mark II Yeti during the Great Intelligence's third attempt at invading Earth. The weapon fired a concentrated string of strong web material. When attacked with grenades, the Yeti could use the guns to cocoon them.
The Yeti also used the guns to spin a giant web that ensnared the Doctor's TARDIS. (TV: The Web of Fear [+]Loading...["The Web of Fear (TV story)"])
A Yeti web-gun was part of the shipment of salvaged artefacts given to the CIA. (PROSE: The Men Who Sold the World [+]Loading...["The Men Who Sold the World (novel)"])
