This is the Pasta Bridge that Munn built!
-Paper for blueprint (11 x 17 inches)
-1/2 box linguine (or spaghetti)
-10-12 glue sticks (4 inch mini's)
-Mini-hot glue (low-temp)
-Block (5 x 5 x 2 cm)
-Eye-hook (with nut and washer)
STEPS TO BUILD YOUR OWN PASTA BRIDGE!
STEP 1: Research Bridge Truss designs. Link to for Bridge Resources (WD-STEM Bridge Site)
STEP 2: Blueprint. Draw an exact drawing of the SIDE-VIEW of your truss.
<<Must "span" 35 cm. (The opening is 35 cm).
*This is an adaptation of the Whipple Truss.
*I added extra diagonal supports to the center (around
where the block will be.)
**In my next design, I'll have the diagonals meet exactly in the center, rather than off-center.
STEP 3: Glue two strands of pasta together the length of the truss along the bottom.
<<THE FIRST TWO STRANDS ARE HERE.
STEP 4: Glue the outside frame and verticals.
STEP 5: GLUE the diagonals. **You can measure them before glueing, OR
as illustrated, glue then cut off the extra...carefully!
STEP 6: Do it again! Make a second truss for the other side.
STEP 7: BLUEPRINT #2: The bottom frame (a.k.a. "the frame for the roadbed/deck)
<<Notice the cross bars of the bottom frame line up with the vertical braces on the truss.
<<Hole in the middle for the eye-hook!
<<Full length spaghetti that crosses next to each other in the middle section (where the block will be!).
STEP 10: Glue bottom frame to one truss. (It's easier to glue together with the truss on its side.)
STEP 11: Glue the other truss on the other side of the bottom frame.
**Make sure the sides are straight up!
STEP 12: Measure how wide the bottom of the bridge is. Break pieces this size to connect the trusses.
Then glue the trusses together with the pieces.
<<Top view. Glued across and diagonally.
STEP 13: Add the block (5x5x2 cm) and eye-hook. Hang over 2 tables with a 35 cm span.
STEP 14: TEST! Put a sheet or tarp under your bridge.
*Attach a large cup or bucket to the eye-hook.
*Slowly add measured weight until it breaks! (or almost breaks...)
