Chalkboard Sphere

This instructable will show you how to build a blackboard sphere to write on. Because sometimes a flat area is not enought!

Step 1: Assemble the Polysyrene Sphere

You have to glue the two pieces together. Pay attention to use a glue intended for polystyrene (some glues can dissolve/liquify it)

Step 2: Add 2 Layer of Cementite (primer)

To make it, I covered a polystyrene sphere with special blackboard painting. I used a cd-r box to hold the sphere in place

Step 3: Add 1 or 2 Layers of Blackboard Paint

Once dry, you can add a layer or two of blackboard paint

Step 4: Add a Support to the Sphere

Use an empty cd box as a stand for the sphere. With a cutter make a small hole and glue the cd-box stick into the hole. I used an hot-glue gun to fill the spaces between the stick and the hole in the sphere
