Query: Strings from Flux Tube Solutions in Kaluza-Klein Theory   We calculate dimensional reduction of gravitational flux tube solutions in
the scheme of Kaluza-Klein theory. The fifth dimension is compacified to a
region of Planck size. Assuming the width of the tube to be also Planck size we
obtain string-like object with physical fields originated from an initial 5D
metric. The dynamics of these fields is inner one.
