Knight's Helmet

Supplies: cereal boxes + aluminum foil + masking tape + invisible tape + glue stick + scissors + X-Acto knife + clear light plastic salad containers to make eye shield + markers + duck tape

How to: 
1) Open top and bottom of two cereal boxes. Find the side seam on each box. Open up and flatten. 
2) Cut off extra flaps.
3) Overlap the two boxes about an inch. Tape the seam with masking tape on both sides. This makes one large piece.
4) Take the piece and wrap it around your head to make a cylinder. Overlap at least 1 inch. You can cut off some if you have too much overlap. Tape with masking tape inside and out. (For larger heads you may need more that two boxes.)
5) Cut out one long or two short rectangles for eyes. As an option, you can cut a piece of clear plastic and put it inside the helmet over the eye openings as a shield.
6) Measure circle for top of helmet using the cylinder you just made. Add about 1/2 inch extra all the way around the circle.
7) Cut out circle. 
8) Go around the circumference and make 1/2 inch cuts into the circle. This will make tabs all the way around.
9) Fold the tabs down.
10) Fit circle into the cylinder. The tabs will go inside. Tape the tabs inside the cylinder with masking tape. This forms the helmet.
11) Measure and cut aluminum foil to cover the helmet.
12) Use invisible tape to secure the aluminum foil to the helmet.
13) Cut out decorative shapes to add to your helmet and cover them with aluminum foil. Tape to helmet.
