How to make a simple windmill - a weather vane from a PET bottle in 5 minutes
To decorate your area, you can make a decorative garden windmill from plastic bottles. It's very easy and fun. This homemade product can be made together with children. If you use colorful, bright, saturated plastic bottles, the windmill will turn out no worse than a store-bought one.
For a 2 liter plastic bottle, the neck is cut off closer to the middle and opens into 8 rays.
It is cut lengthwise, not reaching 2 cm to the lid. The rays are then bent outward to create a bend and aligned at right angles.
Next, you need to bend them diagonally, capturing only the upper corner.
This will give them the characteristic shape of a windmill blade. Due to bending, they will receive a stiffening rib, will keep their shape and respond better to the wind.
The middle of the second plastic bottle is cut out. To do this, the bottom and neck are cut off. The remaining part blooms lengthwise to form a leaf.
The sheet is folded in half and a tail for the windmill is cut out of it.
In the future, if you do not fix the windmill on the stand rigidly, then due to the tail, when exposed to wind, it will be able to turn in the direction of the air flow. To make this happen, the tail must be made wide enough. A bamboo skewer is inserted between the walls of the tail, then the sheets of plastic are fastened with a stationery stapler.
A hole is made in a long tube or pole to fit the diameter of a skewer. Then a skewer with a tail is inserted into it.
A hole is also made in the neck cap of the bottle with blades, but of a slightly larger diameter, and it is put on a skewer.
Then the windmill is fixed with another cover with a hole. To prevent it from flying off, it needs to be glued with hot glue. With this fixation, the structure cannot turn with the wind, so the tail will simply be a decorative element. If you provide on the windmill stand the same axis of rotation as a skewer on the blades, only vertical, then when the direction of the wind changes, the windmill will adapt to it, so it can rotate without stopping. The higher you place it, the more actively it will turn around.
A windmill made from plastic bottles, in addition to decorative and entertainment purposes, can also be used to scare away birds from the area if they are pecking at strawberries, cherries, cherries, peaches, etc. In this case, it needs to be tied above the tree crown or installed on the beds.
Materials:
- plastic bottles 2 l – 2 pcs.;
- long tube or pole;
- bamboo skewer.
