With your knife, make a slice on the bottom to make a flat surface so the watermelon can stand upright for your drink. (You may be able to skip this step if your watermelon already has a flat side and can stand up straight without rolling.)
Then make a slice on the opposite side to remove the top.
With your knife, make vertical slices in the shape of a plus sign and then all around the edges.
Using your ice cream scoop, scoop out as much watermelon as you can and put it in a bowl.
Using your scoop, carefully remove additional watermelon from the rind, leaving the rind so that you can see the white part of the melon.
