Charles studied the volume of a sample of air—sealed in a glass tube with a U-shaped curve—as he systematically changed the temperature by immersing the tube in a water bath. The air was trapped by a …

When the LEDs are turned off, the infinity mirror acts just like a regular mirror. But when the LEDs are turned on, the infinity mirror looks …
