egg beater
 n.— «Most of the fruit is “wet harvested.” The bogs are flooded and special harvesting machines, affectionately called egg beaters, whisk up the water to release the berries, which are full of air pockets and so float to the top.» —“A study in scarlet” by Lila Das Gupta Telegraph (United Kingdom) Oct. 28, 2006.
