What happens when I throw a banana to a running ceiling fan?
The result of throwing a banana at an operating ceiling fan will depend on the ripeness of the banana, the speed at which the fan is rotating and whether or not you have peeled the banana, among other factors. It is possible with a ripe, peeled banana and a fan rotating at high speed that the banana will be cut into two or more pieces. However, it is just as likely to make a mess.

An unpeeled banana will not likely be cut unless you have an extremely powerful fan with sharp blades.
How do I sharpen the blades of a fan?
It's important to note that sharpening the blades of a fan is not recommended, as it can be dangerous and may damage the fan. The blades of most fans are designed to be aerodynamically efficient and balanced, and altering their shape or sharpness can cause them to become unbalanced and unsafe to operate.

However, if you are experiencing issues with a fan that is not working properly or is producing an unusual amount of noise, there are some troubleshooting steps you can take before considering blade sharpening. These may include cleaning the fan, checking for loose or damaged parts, and ensuring that the fan is properly lubricated and balanced.

If you do need to replace the blades of a fan, it is recommended that you purchase new blades that are specifically designed for your fan model. You can typically find replacement parts through the fan manufacturer or a reputable home improvement store. It's important to follow the manufacturer's instructions for installing new blades and ensure that they are properly balanced before operating the fan. If you are not comfortable replacing the blades yourself, it's best to consult a professional or experienced repair person to ensure that the fan is operating safely and effectively.
Let's say I really want to sharpen the blades of the fan, disregarding safety ideas, what would be the best way?
I really like the idea of having the fan slicing a banana. If I cannot sharpen the blades, what can I do?
