@gritgearhq: Some of the most useful emergency materials are probably already sitting around your house. Sand and gravel, charcoal, coffee filters, cloth, activated charcoal, pebbles and stones can all have practical uses when you have to improvise. Knowing how to use ordinary materials is just as important as stockpiling gear. #Survival #Prepping #SurvivalTips #EmergencyPreparedness #Bushcraft
