It’s unlikely that we remember how we reacted to seeing glass for the first time. But watching this video gives you a pretty good feeling of how it might have gone.

Now, we would know that this is for aesthetic and that you can walk right over the glass…but these babies have never seen glass before. And they are very confused. Watch the video below to see their adorable reaction to this glass floor!
