Instructions
Take one of the 1 x 4 bricks (No. 1) and clip it onto another (No. 2) at a 90-degree angle. Take another brick (No. 3) and affix it to No. 2 so it lies at a 180-degree angle from No. 1 and perpendicular to No. 2. Clip the last 1 x 4 brick (No. 4) to No. 3 to form a 180-degree angle from No. 2 that is perpendicular to No. 1 and No. 3. This will be a star fan shape.
Clip the tap piece to No. 1 from underneath. This will provide a base for the fan, and the extended faucet can be used to turn the fan.
Attach the tap piece to the 1 x 1 brick. You can then mount the fan onto the roof of a Lego building.
