A fidget spinner spins due to the principles of physics related to angular momentum and friction. When you apply force to one of the arms of the spinner, it starts rotating around its center. The spinning motion is maintained due to the conservation of angular momentum, which means that an object will continue to spin unless acted upon by an external force. Friction between the bearings and the central axis helps to reduce the loss of energy and allows the spinner to spin for a longer period of time. **

A Fidget Spinner spins due to the principles of physics related to angular momentum and friction. When a force is applied to the spinner, it starts rotating around its center. The spinning motion continues due to the conservation of angular momentum, which means that an object in motion will stay in motion unless acted upon by an external force. Friction also plays a role in slowing down the spinner's rotation over time. **

You should lubricate the Fidget Spinner with a small amount of light machine oil, such as sewing machine oil or 3-in-1 oil. Avoid using heavy oils or greases, as they can attract dust and debris, which can affect the spinner's performance. It's important to use only a small amount of oil to prevent it from leaking onto your hands or other surfaces. Regularly cleaning and lubricating your Fidget Spinner will help maintain its smooth spinning action. **

Yes, you can buy both the Fidget Cube and the Fidget Spinner in many stores. These items are popular stress-relief toys and are commonly found in toy stores, gadget shops, and online retailers. They come in various designs, colors, and materials to suit different preferences. **

The spinning time of a fidget spinner can vary depending on the quality of the bearings and the force used to spin it. On average, a fidget spinner can spin for about 1-3 minutes. However, some high-quality fidget spinners with premium bearings can spin for up to 5 minutes or more. It's important to note that the spinning time can also be affected by factors such as the cleanliness and maintenance of the bearings. **

When a fidget spinner is oiled, the oil can seep into the bearings and cause them to become less effective at spinning smoothly. The oil can attract dust and dirt, leading to a buildup that can further hinder the spinner's performance. Additionally, the oil may break down over time, causing the spinner to become sticky or less responsive. Overall, oiling a fidget spinner can accelerate its deterioration and reduce its functionality. **

Rust forms in the ball bearing of a fidget spinner when the metal in the bearing is exposed to oxygen and moisture. This exposure causes a chemical reaction known as oxidation, which leads to the formation of iron oxide, or rust. The presence of moisture, such as from sweat or humidity, can accelerate this process. Over time, the rust can build up and cause the ball bearing to become stiff or difficult to spin. Regular cleaning and maintenance can help prevent rust from forming in the ball bearing of a fidget spinner. **

To clean the ball bearings of a fidget spinner with WD-40, you will first need to remove the bearings from the spinner. Next, spray the WD-40 directly onto the bearings and allow it to penetrate and loosen any dirt or debris. Use a clean cloth or paper towel to wipe away the excess WD-40 and any dirt that has been loosened. Once the bearings are clean, allow them to dry completely before reassembling them into the fidget spinner. **
