Methods

Materials

1. Balsa Wood (as long as possible for cutting down into size)

(about 50 cm x 0.5 cm x 0.5 cm) (about 6-8 sticks)

2. Hot glue gun (2 glue sticks for hot glue gun)

3. Cardboard base (25 cm x 25 cm)

4. Plastic Container (Diameter of 15-20 cm)

5. Weights (50 kg worth of weights, ranging from 5 kg-20 kg weights)

Risk Assessments

1. Splintering from the wood

(prevented by wearing gloves)

2. Cuts from construction

(prevented by careful use of sharp materials)

3. Fingers or body parts crushed by weights

(prevented by exercising caution when using weights)

4. Burns from hot glue gun

(prevented by wearing gloves and not to use the hot glue near skin)

5. Fingers stuck together from glue

(prevented by wearing gloves)

**Procedures**

Pillar Design:

1. Cut 9 sticks of balsa wood of 20 cm

2. Glue the sticks of balsa wood together in the format of 3x3

3. Cut out 5 sticks of balsa wood of 9 cm

4. Glue them side by side to make a base

5. Layer the top of the base in the opposite direction the balsa wood is facing

(about 14 sticks of 2.5 cm)

6. Stick the structure from step 2 in the middle of the cardboard base as shown

7. Stick the top base from step 5 on the top of the pillar on the cardboard base as

shown below in Fig 4

Criss-Cross Design:

1. Cut out 5 sticks of balsa wood of 9 cm

2. Glue them side by side to make a base

3. Layer the top of the base in the opposite direction the balsa wood is facing

(about 14 sticks of 2.5 cm)

4. Cut out 4 sticks of balsa wood of 20 cm

5. Stick one stick from step 4 to each corner of the base made in step 3

6. Stick the whole structure to the cardboard base

7. Cut 2 sticks of balsa wood of 8 cm

8. Cut 2 sticks of balsa wood of 1.5 cm

9. Stick the 8 cm stick in between and in the middle of the 20 cm pillars where the

gap is the widest of the two sides

10. Stick the 1.5 cm stick in between and in the middle of the 20 cm pillars where

the gap is the smallest of the two sides

11. Cut 4 sticks of balsa wood of 12.8 cm

12. Cut the edges of the 4 sticks so that the ends are in the shape of an arrow

13. Stick the sticks diagonally in between the pillars of 20 cm, both on top and

below of the stick that have been stuck in the middle from step 9 as shown

below in Fig 5.

Tripod Design:

1. Cut out 5 sticks of balsa wood of 9 cm

2. Glue them side by side to make a base

3. Layer the top of the base in the opposite direction the balsa wood is facing

(about 14 sticks of 2.5 cm)

4. Cut out 6 sticks of balsa wood of 22 cm

5. Cut each end of the sticks to be diagonal but each end to be cut in the direction

of the other end

6. Stick four sticks on each corner of the base from step 3, however, stick it in a

way such that the sticks come out of the base at a 45˚

7. Stick the rest of the sticks in the middle of the longest side of the base

8. Finally, stick the whole structure on the cardboard base as shown in Fig 6.

Combined Structure:

1. Cut 9 sticks of balsa wood of 20 cm

2. Glue the sticks of balsa wood together in the format of 3x3

3. Cut out 5 sticks of balsa wood of 9 cm

4. Glue them side by side to make a base

5. Layer the top of the base in the opposite direction the balsa wood is facing

(about 14 sticks of 2.5 cm)

6. Stick the structure from step 2 in the middle of the cardboard base

7. Stick the top base from step 5 on the top of the pillar on the cardboard base

8. Cut out 4 sticks of balsa wood of 20 cm

9. Stick one stick from step 4 to each corner of the base made in step 7

10. Stick the whole structure to the cardboard base

11. Cut 2 sticks of balsa wood of 8 cm

12 Cut 2 sticks of balsa wood of 1.5 cm

13. Stick the 8cm stick in between and in the middle of the 20cm pillars where the

gap is the widest of the two sides

14. Stick the 1.5 cm stick in between and in the middle of the 20cm pillars where the gap is the smallest of the two sides

15. Cut 4 sticks of balsa wood of 12.8 cm

16. Cut the edges of the 4 sticks so that the ends are in the shape of an arrow

17. Stick the sticks diagonally in between the pillars of 20 cm, both on top and

below of the stick that have been stuck in the middle from step 13

18. Cut out 4 sticks of balsa wood of 22 cm

19. Cut each end of the sticks to be diagonal but each end to be cut in the

direction of the other end

20. Stick each stick in the middle of each side of the base

21. Cut out 4 sticks of balsa wood of 8 cm

22. Cut one end of the stick into a diagonal shape

23. Stick each of the sticks on the diagonal beams with the diagonal side of the

stick on the diagonal beam and the flat side on the board as shown below in

Fig 7.
