McCulloch hand vacuum pump

A simple cardboard tube sliding inside another one, the hand vacuum pump was invented in the 1970s by Norma McCulloch of Rongotea in Manawatū. The pump used in kitchens around New Zealand to extract air from freezer bags before the contents are frozen. This saves space in the freezer and improves the quality of the frozen food.
