How to: Build a Bridge By: Noel Vanderbol

Materials

  • 1 -2 bottles of Elmers glue
  • 300-400 Popsicle Sticks
  • 1 package of rubberbands
  • 1-2 boxes of paper clips
  • 1-2 pages of newspaper
  • 3 empty waterbottles

Sides

  1. First, you need to place ten popsicle sticks end to end, and then glue another stick squarely on top of and halfway down two sticks, continue to do this to the end of your first ten to to create your first base line. Do this three more times so you have four baselines.
  2. Second, put paper clips on the ends of all the popsicle sticks that were glued together to keep these sticks in a straight line. Its very important that the base lines are completely straight to make building the bridge easier. (Once everything is dried you can remove the paperclips.)
  3. Next, take three popsicle sticks and glue them into a 45 degree even triangular figure. Repest this step until you have about twenty triangles
  4. Then, you should put paperclips on all the corners to keep the sticks from moving while the glue is still wet. (Once everything is dried you can remove paperclips.
  5. Then, once everything is dried, you can start glueing the triangles to the base lines by putting the bottom of the triangle on top of the base line, and the top of the triangle on the second baseline. Continue to do this with about ten of the triangles. Repeat this step with the other two baselines and ten triangles.
  6. Finally, to prevent the triangles from moving around on the bridge and messing up the alignment, you should again put paperclips anywhere that was glued. (Once everything is dried you can remove the paperclips.)

Securing the sides together

  1. First, and you may need help to hold the sides up, so you can put three empty plastic waterbottles down the center of the sides
  2. Second you will have to cut about ten rubberbands in half so you get long bands.
  3. Then tie one band inbetween two of the waterbottles and tie another band in between the other two waterbottles.
  4. Next put two dots of glue going diagonally and put one stick on these dots.
  5. Fifth you should take two bands and tie them around the ends of the stick that was just glued so it is secured in place before you add the second stick.
  6. Sixth glue another stick diagonally over the first stick so it looks like an X. After the X's are finished and dried it is ok to remove the rubberbands and water bottles.

Top

  1. First, put two dots of glue going diagonally and put one stick on these dots.
  2. Second, you should take two bands and tie them around the ends of the stick that was just glued so it is secured in place before you add the second stick.
  3. Third, glue another stick diagonally over the first stick so it looks like an X.
  4. Continue to make X's going down the top of the project until you feel there are enough to keep the top sturdy. (After a few X's are done it is safe to remove the waterbottles.)

Bottom

  1. First, put two dots of glue going diagonally and put one stick on these dots.
  2. Second, you should take two bands and tie them around the ends of the stick that was just glued so it is secured in place before you add the second stick.
  3. Third, glue another stick diagonally over the first stick so it looks like an X.
  4. Continue to make X's going down the top of the project until you feel there are enough to keep the bottom sturdy.
