Using a foam paintbrush, paint the Styrofoam dome with Pure Black paint. Dry-brush paint the chopsticks. Allow to dry.
Wet the sea sponge and wring till the sponge is damp. Dip into the Gunmetal paint and tap off the excess. Tap the sponge over the dome and chopsticks. Allow to dry.
Push the chopsticks into the dome shape near the base, this will form the legs. Place four 'legs' on each side.
