Do you know what virtual reality (VR) is? VR is something you can experience if you put on a VR headset. The headset lets you see and hear things that make you feel like you're in a completely different place. Perhaps you've seen people using VR headsets or even tried one out yourself. In this video, Margot shows us an object called a stereoscope. It's about 150 years old! What did people use it for? How is the stereoscope similar to virtual reality headsets of today? How is it different?
