An apple corer is a great kitchen tool. This Instructable applies one to a watermelon, but a corer also allows serving various other fruits or vegetables in an original way.
Using this conventional apple corer gives cylindrical shapes up to a length of approximately 7.5 centimeters max (3 inch) and a diameter of 18 mm (0.7 in). A watermelon gives a really nice result because the rind can be cut out as well, resulting in a layered color pattern as can be seen in some of the pictures.
The cumulative mass of the sticks amounts to approximately 70% of the initial weight on the watermelon slice (dependent on the space that is left in between the holes). The leftover part with the holes is perfectly fit for human consumption: don't waste it.
The resulting rounds or cylinders can be used in various configurations, for example as standing sticks (see Step 1), as an Instructables' logo (see Step 2) or as 1.4 dpi matrix characters (see Step 3).
Step 1: Standing Watermelon Sticks
Cut the watermelon in thick slices. The top and bottom part allow making little pillars with the rind still on it. The middle slices give pillars that are red from top to toe.
The next step shows the Instructables' logo made from watermelon pixels.
