So amazing!
That is really cool that concrete uses bacteria to repair cracks. I didn't know that concrete could do that. Those pictures of the crack to watch the repair over time is really cool.

this is a good idea because when I went to Disneyland I saw a lady fall real hard and she almost broke her arm and when I went to see how big the crack was it was big so if they use this type of material then people will avoid falling and getting hurt from a big or small crack.
