the water in the compartments of the hatchery or your container turns dark, that is a sign that it is gone

7.2. Textile fibres
Objects and accessories:
1. Threads of different textiles: Cotton, linen, wool, silk, Celanese, nylon and any others you can find.
2. Two needles:
Put each thread on a glass slide and fray each with the help of the two needles. Put a drop of water
over each thread with the pipette and cover each with a cover glass. Adjust the microscope to a low
magnification. Cotton fibres are of plant origin and look, under the microscope, like a flat, twisted band.
The fibres are thicker and rounder at the edges than in the centre. Cotton fibres consist primarily of
long, collapsed tubes. Linen fibres are also of plant origin; they are round and run in straight lines.
The fibres shine like silk and exhibit numerous swellings along the shaft of the fibre. Silk is of animal
origin and consists of solid fibres of smaller diameter than the hollow vegetable fibres. Each silk fibre
is smooth and even and has the appearance of a small glass rod. Wool fibres are also of animal origin;
the surface consists of overlapping scales, which appear broken and wavy. If possible, compare wool
fibres from different weaving mills, and note the differences in the appearance of the fibres. Experts
can determine the country of origin of wool based on its appearance under a microscope. Celanese
is artificially manufactured by a long chemical process. All Celanese fibres show hard, dark lines on a
smooth, shining surface. The fibres crinkle in the same way after drying. Observe the similarities and
differences between the different fibres.
