While organizing an exploratory walk in Montevideo with the NGO OCAC, we met with Sol its the founder. She explained to us that street harassment was so common in the streets of Montevideo (capital of Uruguay) that she had to do something about it!
They decided to equip themselves with water gun, to respond to harassment! Because like they say :
« Water dries but harassment leaves the print of a violence that grows »
Level of implementation : individuals, NGOs (LGBT, Feminist,…)
Budget : very cheap !
