Prepare the tapioca beads:
In a large pot (Make sure the pot is big enough so boiling tapioca water will not spill over) over high heat, add water and bring to a boil.
Slowly stir in the tapioca pearls so that they do not stick together (after 1 minute, the tapioca pearls should float).
Reduce heat to medium and let boil, covered, for approximately 15 minutes; turn the heat off and let the tapioca pearls site, covered, for an additional 15 minutes.
After 15 minutes, remove from heat, rinse the tapioca pearls in cold water, and drain.
Prepare the tea:
Place the teabags in the boiling water for 5 minutes. Remove the bags before stirring in the honey. Set aside to cool and refrigerate until chilled.
Bring 1½ litres of water to the boil. Add the tapioca and reduce the heat to a simmer for 50 minutes, until the tapioca is tender. Drain and rinse under cold water.
Using a stick blender or liquidiser, blend together the mango flesh with the orange juice and coconut milk. Mix the mango liquid with the tea water and the tapioca. Serve in tall glasses with straws.
