Origami is the traditional Japanese art of transforming paper using folding and sculpting techniques. The word origami is derived from the Japanese word "ori" which means "folding" and "kami" which means "paper." Since origami designs incorporate math components, they can be found everywhere from business advertisements to books. In addition to the traditional crane, modern designs including sea creatures, flowers and bicycles can also be created.
Place paper on a flat surface so the white side is facing you. Fold the paper vertically in half. Crease with a ruler, then unfold.
Turn the paper over so the coloured side is facing you. Fold the paper diagonally so the bottom left corner meets the top right corner. Repeat the diagonal fold so the bottom right corner meets the top left corner. Crease both folds with a ruler, then unfold.
Collapse the paper along fold lines. Press down to secure the folds. This is the square base.
Lay the square base on a flat surface with the corners facing the top and bottom. Fold the left and the right corner together so the sides meet in the middle of the paper. Crease with a ruler, then unfold.
Fold the top of the paper down toward the bottom to create a triangle at the top. Crease with a ruler, then unfold.
Lift the bottom corner of the top sheet of the paper upwards to create the petal fold. Fold along the creased lines along the left and right side. Flatten the fold to form a triangle.
Flip the paper over so the coloured side is facing you. Fold the left and the right corners together so the sides meet in the centre. Use a ruler to crease the edges, then unfold.
Repeat Step 6. Flatten the fold to form a long triangle.
Pull the top two flaps apart from each other until the centre flattens out to form a triangle.
Push the centre of the square down. Use a ruler to crease the edges. Two of the flaps will stick up.
Pull the inner layer of the paper outward to reverse the folds on the right side. Do the same with the left side of the paper.
Rotate the paper 90 degrees so that it lies horizontal on the surface. Fold the left flap upwards in a 45-degree angle toward the centre of the paper. Use a ruler to crease the edges.
Fold the tip of the piece you have just folded toward you. Use a ruler to crease the edges. Do not unfold the edges. This piece forms the saddle of the bike.
Tuck the tip of the saddle in by folding it under. Fold the left side of the seat post to meet the right side. Use a ruler to crease and leave the edges folded.
Insert an index finger under the top layer of the paper, which opens up the flap. Fold the right side of the paper toward the left so the bottom edges of the paper align and form a crease in the centre. Use a ruler to flatten the fold.
Lift up the bottom portion of the paper toward the base of the seat and flatten the flap. Use a ruler to secure the crease and leave the paper folded.
Pull out the inner flap and fold it along the existing centre crease.
Fold down the top portion of the flap so the edges align with the bottom of the paper. This becomes the chain ring.
Fold the bottom portion of the paper up toward the right side to meet the right corner of the fold. This fold forms a small square. Flatten the crease with a ruler.
Fold both flaps below the seat post to align the edges at the centre crease. Fold the left side of the paper away from you to form a crease that bisects the triangular piece in half.
Reverse fold the coloured triangle beneath the square fold of the paper. "Rabbit Ear" fold the tip of the triangle.
Fold in the four corners of the square toward the centre. Use a ruler to flatten the small folds.
Fold the right tip of the paper away from you toward the centre at the back of the paper. Use a ruler to secure the crease. This is where the front wheel will attach to the frame of the bike.
Take out two sheets of paper. Fold a "Water-Bomb Base" for both wheels. Fold the top layer of the paper toward the bottom so the tip meets at the bottom edge.
Crease and pull up the top layer of the paper. The corner of the paper will pop out. Fold the side toward the centre and crease.
Fold the left and right corners toward the centre of the paper so that the edges meet in the centre. Use a ruler to crease the fold. The paper should look like a triangle.
Flip the paper over. Fold the top portion of the triangle toward the bottom of the paper.
Insert fingers in the pockets on either side of the centre point to inflate the triangle. Use a ruler to crease the fold.
Fold the right panel toward the centre of the paper. Crease with a ruler and leave the paper folded.
Reverse fold the bottom of the right flap away from you. Fold the flap in half so the right side aligns with the left side. Fold the paper again vertically in half.
Repeat Steps 6 and 7 with the left side of the paper.
Flip the paper over. Fold up both loose flaps toward the top. Use a ruler to crease the edge, then unfold.
Fold in the bottom corner of the flap. Tuck the tips of the loose flaps
into the pocket created from folding the corner.
Fold the left and the right corners away from you toward the centre of the square. Use a ruler to crease, leave folded.
Flip the paper over. This becomes the rear wheel. Repeat the steps for the front wheel.
Fold the left vertical flap of the front wheel up toward the left corner and fold the right flap up toward the right corner. This will become the handle bar and the joint to connect the front wheel to the bike frame.
Rotate the rear wheel so the long flap inserts into the space beneath the seat of the bike.
Slide the left handle bar of the front wheel into the pocket on the right side of the bike body.
Fit the two wheels snugly into the body of the bike.
Different patterned or coloured sheets of paper can be used for the design.
