Knives manufactured from frozen human feces do not work

Knives manufactured from frozen human feces do not work.

Would it be impolite to say no sh*t?

Although the fact it did not work gave it away.

“In order to procure the necessary raw materials for knife production, one of us (M.I.E.) went on a diet with high protein and fatty acids, which is consistent with an arctic diet, for eight days…”

“Raw material collection did not begin until day four, and then proceeded regularly for the next five days (Table S1). Fecal samples were formed into knives using ceramic molds, “knife molds” (Figs. S1–S2), or molded by hand, “hand-shaped knives””

“We repeated the experiment using the fecal samples of another team member (M.R.B.), whose diet was more traditionally Western (see supplementary online materials)”
