If it seems like you're seeing glass-bottomed attractions all over the Internet, it's because, well, you are.
Photos of yet another glass-bottomed walkway in China took over (parts of) the Internet last week, leading us to the inevitable conclusion that glass-bottomed anything has been deemed the way to attract tourists.
The bridge in question looks like it's in a cloud (and may or may not occasionally sway in the wind).
And over in Paris, the newest addition to the Eiffel Tower is a section with glass floor paneling. It doesn't exactly sway, but the paneling (and the selfies people have been taking on it) is still totally unnerving.
If neither of these are scary enough, there's always the Peak Walk, a Swiss Alps attraction that, when completed, will hang about 10,000 feet above the ground with partial glass paneling. Once it opens to the public, we think it might be this scariest attraction of all.
