Researchers Made 25-Ton Boulders They Can Move by Hand

How were giant ancient structures like Stonehenge, or the towering Moai heads on Easter Island, assembled at a time when cranes and trucks were still hundreds of years away? Researchers at MIT have given more credence to theories that ancient engineers were masters of balance and leverage with a new experiment that produced giant concrete structures, some 25-tons in weight, that can be still be maneuvered by hand. Matter Design (which was co-founded by Brandon Clifford, who’s also an assistant professor at MIT) worked with CEMEX, a company that specializes in building materials, to design a series of over-sized concrete monoliths that could be assembled like giant building blocks into a larger, functional structure.
