Using an intercom lowered 2,300 feet, the miners explained that they carefully rationed the food that had been stored in the emergency shelter, eating "two little spoonfuls of tuna, a sip of milk and a biscuit every 48 hours," according to a member of the rescue team. Rescuers have managed to deliver glucose, hydration gel, oxygen, and medicine to them using plastic supply tubes. "They asked for food, and toothbrushes and something for their eyes," says the mining minister.
