20 SBD Science Challenge

Here is a simple video of some water flowing off a ball & landing onto a crudely carved wood map.

My challenge to you is to create a map on a ball that holds water like we are taught our earth does.

If it proves to daunting of a task for anyone to make a map of our earth function like we are told our earth does, I will donate the 20 SBD to @canna-curate & support medicinal plants on steemit.
