Google offers this free app that turns your phone into a VR headset. It's very cool! And you can then take VR tours where you are an astronaut in outer space or a hiker exploring a forest. The list of videos is endless.
You just need this little cardboard viewer. Make sure you get the V2 and not the first version. I bought them for Shoppee for SGD$6 and they were delivered in two days. I plan to use them throughout the year to "explore" different places.
Then girls just have to load the app onto their phone. https://shopee.sg/Google-Cardboard-V2-Version-2-Virtual-Reality-(VR)-3D-Glasses-VR-Box-With-Free-Head-Band-i.10137505.4801080258
