Electric pollination

American scientists have found a
way to give pollen grains an electrostatic charge to improve pollination.
The charge attracts the pollen to
plants, they say. The pollen is stored
in a tank and pumped through a
hollow electrode, after mixing it
with distilled water and salt. A high
speed air stream is used to turn the
mix into a fine spray. The charged
mix deposits nearly five times as
much pollen on the plants as did
spraying with uncharged pollen.
