Poland's trade union Solidarity is eyeing the South African vuvuzela as an attention-getter to use at protests, the daily Metro reported Thursday.
The South African horn, which can not be overheard at the current football World Cup, has caught the eye of the labour union once lead by Lech Walesa, famous for his anti-communist protests in the 1980s, DPA reported.
"If we don't surprise people with anything during protests, and if protests are quiet, then nobody notices them," said Marek Lewandowski, a close aid to Solidarity's leadership.
Other unions also said the loud horn will boost their current arsenal of sirens and horns already commonly used during protests.
"We will already be armed with vuvuzelas in the autumn," said Grzegorz Ilka, of the All-Poland Alliance of Trade Unions. "We will hand these horns out to union members before protests. For a protest of 7,000-10,000 people, some 200-300 instruments will be enough."
Poland did not qualify for the World Cup in South Africa, but the deafening horns have also proved popular for Internet retailers.
"I get orders for 200-300 pieces a day," retailer Adam Bielak told the Metro daily.
