### Materials Needed:

- 280 popsicle sticks
- Elmer's glue bottle
- Rubber bands
- Paper clips
- 3 empty water bottles
- Newspaper
- Flat surface to work on

### Steps:

#### Beams

- Begin by finding a flat surface such as a table and laying 1 layer of newspaper on top.
- Start by laying 4 popsicle sticks in a straight line on the table.
- Apply glue to one side of 5 more popsicle sticks.
- Place those 5 popsicle sticks, overlapping the bottom layer evenly with the ends longer, on top of the 4 sticks.
- Repeat steps 2-4 on top of this.
- Next, repeat steps 2-5 three more times to make 4 total beams with 18 sticks each.
- Let these dry for 10-12 hours depending on how much glue you applied.

#### Triangles

- Second, begin to make a triangle out of the popsicle sticks using 3 per triangle and glueing the ends together evenly.
- Make a total of 20 evenly shaped triangles.
- Use paper clips to hold the pieces together after you have glued them if it is needed.
- Let them dry for 6 hours.
- After they are dry take the paper clips off.

#### Side Connectors

- While all of this is drying, lay 7 popsicle sticks down next to each other so that they are vertical.
- Glue 2 popsicle sticks horizontally but evenly spaced apart with the ends hanging out on top of those 7 sticks. (See picture below)
- Add another layer of 7 popsicle sticks just like the first layer on top of the 2 by applying glue to the other side of the 2.
- Repeat steps 1-3 three more times to make a total of 4 side connectors.
- Allow 6 hours of drying.

#### Top and Bottom

- Begin by gathering 18 sticks.
- Place 2 popsicle sticks in an X with one overlapping the other.
- Glue them together in the center.
- Repeat steps 2-3 eight more times making sure all the X's are the same shape and size.
- Glue each X together by applying glue to each end and overlapping slightly. (See picture below)
- You can use paper clips to hold the pieces together if it is needed.
- Repeat steps 2-5 to create a duplicate trying your best to make them the same size.
- Let them dry for 10 hours.

#### Connecting the Beams, Triangles, and Side Connectors

- After you have waited the amount of time each piece needed to dry gather them all together.
- Get 2 beams, 2 side connectors, and 10 triangles.
- Add glue to both sides at the end of a beam.
- Put a side connector on each end of the beam.
- Slide the ends of the beams into the gap of the side connectors on both sides so that they are intertwined together. (See picture below)
- Make sure the beam is near the bottom of the side connectors.
- Do this again with another beam connecting it to the top of the side connectors so that the 2 beams are connected at both ends.
- Next apply glue to one whole side of a triangle and at the tip that does not already have glue.
- Place the triangle between the 2 beams about an inch away from the end of the beam.
- You can use paper clips to hold the triangles down if you need to.
- Repeat steps 8-9 with the rest of the 9 triangles alternating upside down and upright.
- To build the next side repeat steps 2-10 again.
- Allow this all to dry for a day.

#### Adding Water Bottles

- After the sides are completely dry lay them on top of each other and gently slide 6 rubber bands around them both. (Make sure they are evenly spaced apart)
- Then push an empty water bottle between the two sides and stand it upright. (This may be difficult to get the water bottles to fit. You will need to use a little bit of force)
- Do this with 2 other empty water bottles. One on one end, one in the middle, and one on the other end.

#### Adding the Bottom

- Flip the bridge upside down.
- Apply glue to the the whole bottom side of the beams.
- Place one of the top and bottom pieces down on area that the glue is applied making sure it is in the middle.
- Tie rubber bands around as many places as possible. (See pictures below)
- Allow 8 hours of drying.

#### Adding the Top

- After waiting 8 hours for the bottom to dry, untie any rubber bands you used before.
- Take off the rubber bands around the bridge. You may need to cut them off if it is easier.
- Gently slide out the water bottles.
- Take the glue and apply it to the top beams.
- Place the last top piece on top of the area with glue. Make sure it is in the middle.
- Tie rubber bands wherever they are needed to hold the piece down.
- Let this dry for 8 hours.
- Take off any extra rubber bands or paper clips that are left.
