Working outdoors or in a very well ventilated area, affix one section at a time to the inside of the umbrella with the spray glue (spraying the umbrella and then placing the mylar pieces).Using the template you made, trace enough sections onto the mylar to cover the inside of your umbrella.Using the craft paper make a template of one of the triangular sections of the inside of the umbrella. The angle can be adjusted for the sun conditions. When cooking, draw the four panels up and clip.Glue the plywood bottom piece in the center. Lay out the four panels with the uncovered corners meeting in the middle (see diagram above).Decorate the other side of the four panels if desired.A rubber craft roller or a plastic identification card works good for this. Work out all the bubbles to make the finish as smooth as possible. Glue mylar to one side of vinyl (or poster board) leaving 3″ triangle on one corner uncovered (this is where the bottom will be glued to the panels).Spray paint one side of the bottom piece (plywood or heavy cardboard) with high temperature grill paint. binder clips or clothespins (4 per cooker).sponge brushes or disposable type paint brushes.8″ square 1/8″ plywood or other stiff material (an 8″ diameter metal or ceramic plate can also be used).sheet mylar–available as camping ‘space’ blankets.14″ x 14″ sheet vinyl, poster board or sheet.Wrap all of the edges with transparent packing tape.Ĩ. Smooth the foil down flat and fold the edges around the cardboard.ħ. Glue the foil to the cardboard, shiny side out.Ħ. Cut out a piece of foil, roughly 3/4 of an inch larger than the cardboard piece.ĥ. Use this as a pattern to cut out a piece of heavy cardboard.ģ. Cut along any dotted lines (made of triangles)Ģ. If treated gently, an Eagle will last four or more years.ġ. There are eleven sections held together with duct tape. The cardboard is then cut along the traced lines and covered in foil. This PDF file has a set of pages which are intended to be printed out and traced onto heavy cardboard. Panel cookers can be easily made in the classroom from inexpensive materials, and are simple to use for cooking on clear sunny days. The temperature inside the pot of a panel cooker can reach and maintain boiling. The air inside the bag that surrounds the pot is the insulation that retains the heat. They use reflectors to “gather” a larger area of sunlight and direct it towards a black cooking pot that is placed in a high temperature oven bag. Panel cookers can cook the same foods that you would cook in a covered pot on top of the stove. The rod or stick is used to adjust the tilt of this lid to capture more sunlight. Attach the box lid by one long edge to the oven with an aluminum tape ‘hinge’.Place the glazing on the top of the oven.Cover the inside bottom of the oven with black construction paper.Cover the inside of the box lid with foil for a reflector.Tape all seams: bottom, sides, and around the inside top of the box.Put pieces of insulation around all the walls of the inside of the box.Put a piece of insulation inside the box on the bottom.Foil backed foam insulation board, approx.File storage box, or other box approx.Box ovens can be easily made from inexpensive or recycled materials, and are suitable for classroom construction and cooking. Commercially made box ovens can reach 400o on a clear sunny day. They use reflectors to concentrate more sunlight into the box, glazing to allow sunlight into the box and then trap the heat, and insulation to retain as much heat as possible. As the name suggests, they have an interior chamber (“box”), although it does not have to be square shaped. Box cookers (also known as box ovens) can cook the same foods you would cook in a standard oven or a slow cooker.
