McCulloch hand vacuum pump

McCulloch hand vacuum pump

A simple cardboard tube sliding inside another one, the hand vacuum pump was invented by Norma McCulloch of Rongotea in the Manawatū, in the 1970s. The pump is still 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.
