Straw

A straw was a long, thin tube used for sucking up liquids into the mouth.

The Plasmavore known as Florence Finnegan used a straw to drink the blood of others. (DW: Smith and Jones)

The Eleventh Doctor particularly enjoyed drinking at least some beverages through straws, and even had a favourite, "special straw", which he kept onboard the TARDIS. (DW: The Impossible Astronaut)
