TO BUILD A BRIDGE
JASON MORRIS
MATERIALS
2 PIECES OF CARDBOARD (24" X 20")
2 PIECES OF GRAPH PAPER
ROLL OF WAX PAPER
TOOTHPICKS AND GLUE
TAPE
KNIFE
PROCEDURE
TO START, FIRST YOU MUST DESIGN A BRIDGE ON A PIECE OF PAPER. ONCE THE DESIGN IS CREATED IT MUST BE TRANSFERRED TO THE GRAPH PAPER TO FULL SCALE. THE SIDES, TOP, AND BOTTOM SHOULD BE DRAWN SEPARATELY, THAT IS, SIDE VIEWS OF THE SIDES AND OVERHEAD VIEWS OF THE TOP AND BOTTOM. THESE WILL BE USED AS TEMPLATES.
TAPE THE GRAPH PAPER DRAWINGS TO THE CARDBOARD AND COVER EACH WITH THE WAX PAPER. THIS WILL KEEP THE GLUE FROM STICKING TO THE PAPER DRAWINGS.
TO BUILD EACH SECTION OF THE BRIDGE PLACE THE TOOTHPICKS ON THE WAX PAPER IN ALIGNMENT WITH EACH TOOTHPICK ON THE DRAWING AND GLUE INTO PLACE CUTTING THE TOOTHPICKS AS OFTEN AS NEEDED TO MAKE EACH PIECE FIT. ALLOW TIME TO DRY AND THEN CAREFULLY REMOVE THE WAX PAPER FROM EACH SECTION.
WHEN ALL SECTIONS ARE COMPLETED, FIT THEM TOGETHER AND GLUE INTO PLACE.
TO KEEP THE SECTIONS TOGETHER WHILE THEY DRY WRAP TAPE OR RUBBER BANDS AROUND THE JOINTS OF EACH SECTION. ALLOW SUFFICIENT TIME FOR THE GLUE TO DRY THEN REMOVE TAPE OR RUBBER BANDS AND DISPLAY YOUR BRIDGE.
