So you put a message into this device and then you roll it on the wall, and it basically has all these solenoids pressing the buttons on spray cans, so you just pull it over a wall and it just writes on the wall all the political messages.
Introduci un mesaj în aparat iar el are niște solenoide care apasă pe butoane de spray colorant, îl tagi pe perete şi el scrie toate mesajele politice.
