本物の銀の槍を作って【毒ガス】に反応するか危険地帯に潜入！Dr.STONE

Real silver reacts to hydrogen sulfide and turns black... It was introduced in Dr. Stone as a poison gas detector. To see if it really does turn black, we made a spear out of real silver and went to a poison gas generating area to conduct an experiment! ★Silver mask https://genkilabo.thebase.in/ GENKI LABO x hamon AG collaboration mask (anti-viral x silver antibacterial and deodorizing) is now available!
