Cut the honeydew melon in two pieces. Remove the skin of one of the two parts with a knife. Cut the pear in half and remove the core. Put the skinned half honeydew in a blender together with one cm of ginger and a half pear. Fill your long drink glass half with ice and pour the juicy into it, until it fills the glass for 3/4. Add club soda water till the glass is full. Your healthy ginger beer is ready for consumption!
