A house made of urine and bacteria? Why not, and then more...

"If you will, it is no fairytale", as a wise man said once. And here is another example of will creating something new - from sand and urine this time:

The student tested it with one of the world's most abundant resources - sand. Pumping bacterial solution into a sand-filled mould, he added nutrients, urea as fertilizer and calcium. After a year, and hundreds of failed experiments, this process manufactured a stool* around 70% the compression strength of concrete.
So, we might learn that the expression "laying a brick" had changed its meaning too and that everyone, with some moderate effort, will be able soon to build a house of own bricks.

(*) Just to make sure: "stool" in the context of the above means "A simple seat without a back or arms" and not "Solid excretory product evacuated from the bowels".
