When you can't find a bandage when you're out and about or just roughing it outdoors, a dab of super glue will be able to do the trick of patching you up if you get cuts and blisters.
Clean the wound and stop the bleeding first, then apply a small amount of super glue to the area and quickly spread it around before it dries. It will harden into a mesh that will act as replacement skin until your body is able to heal itself.
And because its non toxic, its alright, but it might cause some minor skin irritation and it takes a long time to come off. Only use this trick if there are no proper bandages available.
