Virtual reality is not just for adults. Companies such as Mattel are trying to make VR kid-friendly. The company has released a cute virtual reality headset that works with Google Cardboard. You will just have to slide your smartphone into the viewer to get started. The headset has a View-Master shell and is pretty easy to use.
The device lets your kids experience 360-degree content on their smartphone. They can interact with the environment by clicking the lever. You can get yours for under $30 at this time.
