A few weeks ago, we showed you a terrifying Alpine tourist attraction called "Step Into the Void". It's a glass cage that hangs more than 1000m above the mountains. But the Void is hardly the first heart-stopping skywalk -- in fact, these are dozens out there that are just as scary.

I'm not afraid of heights, but I don't know how would I react to "Step Into the Void". Experts say that our brains get a bit confused in such environments, and often need some time to acclimate to the new, physics-defying situation it's in. Even if you're not near the Alps, you can test yourself below -- we've collected 14 more or less similar skywalks from around the globe. Enjoy the view!

And here's the glass cage named "Pas dans le Vide" (Step into the Void) at the top of the Aiguille du Midi peak (3842m high) that I mentioned earlier. Visitors can enjoy the view of Mont Blanc, Europe's highest mountain, from the platform, which just ousted the Grand Canyon Skywalk as the highest glass floor above ground on Earth.
