Ant-hills. We've probably all seen it in our lifes. We hope you have not experienced what it is like to step on a bunch of red ants... Auch! But what you probably have not seen in your life, is what is going on underneath an ant-hill. How do you find out? Throw liquid aluminium in the opening of the ant-hill, dig it out and wash the sand off with water. You will get to see the structure of all little allies and chambers the ants have build. This is impressive!
This is so cool!!! Watch the video below, it will blow your mind!
