Items you'll need:
Several large sections of cardboard (I used 3 or 4)
Christmas lights (I used 2 separate strands of chasers)
Aluminum foil (heavy duty works best)
Thin wooden dowels
Plenty of duct tape
Spray on glue if you have it (plain white if you don't--just go thin)
Glow in the dark paint
Putty spreader / bowl scraper
Nail set punch that's a bit smaller in diameter than your lights
Small screw and string
Hot glue gun (for dome top)
Plastic candy bowls (to make the dome top)
CD Player and CD of alien crash sounds
Step 1: The Plan
The cone shapes on the right side were supposed to be the top of the saucer, but it never came together.
This thing requires 3 or 4 large sheets of cardboard.
I scrounged some from packaging for several big mark boards that were ordered at my office. Other places to look include furniture stores and appliance stores.
Step 2: Make the top and bottom
Tie some string to a small screw and your marker. Snug the screw into the cb and trace the circle with the marker.
Cut out with xacto knife. Make 2 circles.
