Stefan Pabst turned a pencil and piece of paper into this glass of water The video of Stefan Pabst, 35, drawing a ludicrously realistic 3D glass of water went viral after he posted it on YouTube.

Paint the jar with one coat of primer (I'm using Gesso). This will ensure your paint adheres to the glass. When the primer is dry, use a pencil to doodle your design on the jar.
