Windmill Construction and Functionality

In this video, Warren demonstrates how to create a convection, heat-powered windmill using simple tools and materials. The process involves downloading a template for the fan blades, cutting and decorating them, attaching them to a shaft, and constructing a stable base using a toilet roll and card. The video emphasizes safety precautions when placing the windmill on a heat source. The tutorial is designed to be easy to follow, encouraging viewers to engage in a hands-on project.

What is the first step in creating the convection heat powered windmill?

• Downloading the template

• Cutting the fan blades

• Decorating the windmill

• Assembling the base

What should you do after cutting a square around the circle on the template?

• Attach it to the shaft

• Glue it to a piece of card

• Cut along the dashed lines

• Decorate the fan blades

What is the purpose of scoring along the dashed lines on the fan blades?

• To decorate them

• To attach them to the shaft

• To help them fold properly

• To make them easier to cut

How do you ensure the fan blades are securely attached to the shaft?

• Use glue

• Use Blu Tac

• Use tape

• Use a rubber band

What is the role of the kebab stick in the windmill construction?

• To act as the fan blade

• To stabilize the base

• To decorate the windmill

• To serve as the shaft

What is the main function of the windmill's propeller?

• To provide decoration

• To cool the air

• To spin as heat rises

• To generate electricity

What is used to make the hole in the center of the card for the windmill base?

• A nail

• A drawing pin

• A screwdriver

• A pencil

Why is it important to make the hole in the base slightly larger with the kebab stick?

• To allow for decoration

• To fit the fan blades

• To ensure stability

• To make it easier to assemble

What should you do before placing the windmill on a heat source?

• Ensure it is decorated

• Make sure it is heat resistant

• Test the fan blades

• Check the glue is dry

What should you use to fasten the decoration around the toilet roll?

• Rubber bands

• Glue

• Blu Tac

• Selotape
