Also the way it self heals is Amazing!!!!!!!!!!!! But also I think they should lower the price so that more people can buy it! But other than that, this article is AWESOME!
techie410년 이상This was really cool to read, for example how the bacteria creates calcite to repair the cracks. It was hard to pick what kind of bacteria to use because most options would die from moisture. First the crack hits a certain point to were it "initiates" the bacteria. Then the bacteria then produces calcite to repair the crack. Finally the crack is slowly repaired and it would also be to expensive for widespread.
sportsguy410년 이상I think it's awesome how they have a self healing bacteria rock/ mineral. It was cool how the Romans used this rock a long time ago. It was amazing that the Romans used this along time ago and we juist figured it out now. I wonder how you use it. this will probelbly win an award.
