Activists have weaponized potatoes.

Members of the anti-fossil fuel group Letze Generation recently used the root crop in protesting against authorities' inaction against global warming.

Four LG members entered the Barberini Museum in Potsdam, Germany to see the Claude Monet painting "Les Meules" displayed there. Two of them then threw mashed potatoes at the prized painting valued at $110 million, Marca reported.

The other protesters recorded the "attack" and posted the video on social media to send the message that "fossil fuels are killing us all," according to Marca.

The painting's glass shield, however, protected Monet's work from damage. The activists were removed from the museum after vandalizing the exhibit.

When unmashed, potatoes can be dangerous to one's health.

Australians Trent Phillip Green, 19, and Brandon John NutuMicicoi, 20, were arrested on 11 October and charged with causing grievous bodily harm, news.com.au reported. They also were indicted at the Perth Magistrates Court on the same day.

Green and Micicoi allegedly attacked a 28-year-old man in the city of Trigg in Perth at about 9.30 a.m. on 20 May, Fox News reported.

From a moving car, they threw potatoes at some e-scooter riders. One rider was badly hit and crashed, fracturing his arm and suffering facial injuries that required surgery to remove his eye, according to Fox News, citing a police statement.

The victim is now half-blind.

Police Inspector Brett Baddock said the attackers just wanted to have fun in using potatoes as projectiles for visitors to their coastal town.

With the tragic consequence of the incident, additional charges were filed against Green: Endangering the life, health, or safety of any person, and possession of a prohibited weapon.
