Virtual reality has other uses aside from video games and other forms of entertainment. Google recently offered another virtual reality tour of historic site, Buckingham Palace, one month after the tech giant released a White House virtual reality tour. The virtual reality version of the Great Barrier Reef is also released along with the Buckingham Palace.

Google's new Expeditions Pioneer Program allows students to take field trips all over the world without living their rooms through virtual reality. Google recently released two locations for the program, namely the Buckingham Palace (London) and the Great Barrier Reef (Australia).

Children will now be able to swim around the world's largest coral reef system and they do not need to suit up any diving equipment. Sir David Attenborough and Alchemy VR created the virtual reality version of the Great Barrier Reef.

"The Great Barrier Reef is a wonder of the natural world and I've been fantastically privileged to visit twice," Attenborough said.

The Buckingham Palace Expedition allows viewers to explore the royal residence's interior. There are guides that will give information about the secrets of the place. Master of Household to the Sovereign Admiral Charles Anthony Johnstone-Burt is available for interested students who wants to have an intimate moment at the home of the Queen of England.

Anna Reynolds also joins Master Johnstone-Burt in guiding the virtual visitors. Anna Reynolds is Buckingham Palace's official curator of paintings.

The Expeditions Pioneer Program was first launched in September, and there are already 500,000 students who had experienced the program. There are lots of requests for many more locations like Buckingham Palace.

The Buckingham Palace Expedition is duly created in partnership with the Royal Collection Trust. The Buckingham Palace is also available for Cardboard customers outside of the education market exclusively on YouTube.

There is also an Android app dedicated to streamline the program's service.
