Here is the question :
WHAT OBSERVATION TOWER HAS THE WORLD’S FIRST REVOLVING GLASS FLOOR?
Here is the option for the question :
- Central Radio & TV Tower
- Liberation Tower
- Seattle Space Needle
- Zhongyuan Tower
And, the answer for the the question is :
[STC002675] ‘The Loupe’ is the world’s first and only (as of January 2019) revolving glass floor, and it’s featured in the Seattle Space Needle. The level was only just inaugurated in August of 2018, giving guests an exciting opportunity to view the city from an elevated vantage point that is 500 feet in the air. Because the floor of the observation deck is see-through, guests will have the impression that they are floating through the air. Not only that, but it spins… not very quickly, of course; it takes around half an hour to complete a full rotation. Despite this, the new attraction will undoubtedly make the one million tourists who visit the Space Needle each year feel as though they have been transported to another world.
