Takeaways

• 😀 You can make a simple pinwheel using a sheet of A4 paper and a few basic materials.
• 😀 The materials needed include: A4 paper, a ruler, scissors, push pins, a cork, and a box.
• 😀 Start by folding the A4 paper diagonally from corner to corner to form a triangle.
• 😀 After folding, open the paper and fold the opposite corners in the same way.
• 😀 Use scissors to cut each corner of the paper towards the center, stopping halfway.
• 😀 Fold each of the cut corners toward the center and secure them with push pins.
• 😀 Insert the push pins from the outside in to attach the folded corners to the center.
• 😀 After securing the corners, fix the pinwheel to a cork or small piece of wood.
• 😀 Test the pinwheel by blowing air on it or placing it in front of a fan to make sure it spins.
• 😀 Ensure the push pin attaching the pinwheel to the cork is not too tight, allowing it to spin freely.
• 😀 Once complete, the pinwheel can be enjoyed as a decoration or used in windy environments for a fun effect.

Q & A

What materials are needed to make the catavento (pinwheel) in this tutorial?

You will need an A4 sheet of paper, a ruler, a small box, a cork, a pair of scissors, and a pushpin (tachinha).

How do you start making the catavento?

The first step is to fold the A4 sheet of paper by bringing one corner to the opposite corner and creasing it. Then, fold the other corner the same way.

What is the purpose of the scissors in the tutorial?

The scissors are used to cut halfway along each of the four corners of the paper to create the pinwheel shape.

What should you do after cutting the corners of the paper?

After cutting the corners, take each of the four edges and secure them to the center using the pushpin, working from the outside edges inward.

What is the significance of the center of the folded paper?

The center of the folded paper is where all the edges meet and where you will fix the pushpin to hold the pinwheel together.

How do you attach the pinwheel to the cork and box?

Once the pushpin is inserted at the center, the cork is attached to the back of the pinwheel. The small box is then placed to help keep the cork in place, leaving a small space between the cork and the box.

What is the purpose of the box in the pinwheel assembly?

The box acts as a stand for the pinwheel, helping to hold the cork in place while ensuring the pinwheel can rotate freely.

How can you test if the catavento is working?

To test the pinwheel, place it in front of a fan or air conditioning vent. The airflow will cause the pinwheel to spin.

What should you observe during the testing phase of the catavento?

When testing the pinwheel, observe the spinning motion of the blades when exposed to airflow, confirming that it is working properly.

What advice does the creator give at the end of the video?

The creator encourages viewers to give the video a like if they found it helpful and wishes them good luck in making their own pinwheel.
