Example Input: Bees find a place for the hive, such as a rock crevice or tree branch. Bees gather nectar from flowers. The bees evaporate the nectar by passing it back and forth to each other. The evaporation turns the nectar into sugary honey. The bees chew the honey until it turns into moldable wax. The bees mold the wax into hexagonal (six sided) cylinders. Thousands of these hexagonal cylinders put together form the hive. 
Example Output:
bees ,nectar ,honey ,wax ,cylinders ,hive
