In Moscow, protesters wear blue plastic buckets

Here's a story that caught my eye today: In Moscow, a group of protesters were arrested over the weekend while wearing blue plastic buckets on their heads. According to Sky News, the blue buckets represent the blue strobe lights that VIPs use on their cars to ignore speed limits and traffic laws. The "blue bucket head" demonstrations are spreading -- the story notes that "demonstrations in Moscow and St Petersburg on April 24 and April 28 sparked traffic mayhem as columns of cars with plastic buckets on their roofs blocked streets." In the latest demonstration, the protesters were arrested because their rally was not approved in advance by authorities. To me, the "blue bucket head" protests bring to mind another set of demonstrations against authority from Moscow that had a tangential connection to plastics: the Prague Spring protests in 1968 that spawned the underground rock band "The Plastic People of the Universe."
