#1391: BraziLoom

Today’s invention makes use of the Brazil Nut Effect in which a jar containing a range of different-sized nuts will, when agitated (in a gravitational field), end up with the biggest nuts on top

Instead of nuts, we use large beads with a specially streamlined shape, together with spherical small ones.

Each of the large beads contains a reel of thread or tape which unwinds as its bead is propelled upwards relative to the small ones. This results in a thread running vertically downwards beneath each of the large beads on the surface. Turn the container through an angle and repeat the agitation. A new set of parallel threads will form.

Manipulating the container in 3-D can drive the large nuts under and over existing threads, forming a warp and weft structure.

When this is sufficiently dense, the small beads can be allowed to flow out of the container -leaving a self-organised fabric behind.
