Creating the bridge
  1. Grab the 2 yard sticks and lay them down on the newspaper but on opposite sides

  2. If needed, paper clip the sticks
  3. Give time for glue to dry
Making the triangles
  1. After the sticks are dried, start making the triangles
  2. Take 2 sticks and put them on the corners to make the triangles
  3. Continue to do this until you get half-way down the lines, then start making them the other way
  4. Repeat steps 2-3 for the other side
Putting the 2 sides together
  1. After the glue on the triangles are dried, you'll want to start putting it together
  2. Take 2 Kleenex boxes and lay them flat spread apart end to end
  3. Take the 2 sides and put them as close as you can to each other in either side of the boxes
  4. You may want someone to help you
  5. Take the rubber bands and wrap them around the bridge and boxes to keep it together
