🤔 How it works …….. ⁉
HOW TALCUM POWDER IS MADE?
Talcum powder is made from talc, a mineral made up mainly of the elements magnesium, silicon, and oxygen. As a powder, it absorbs moisture well and helps cut down on friction, making it useful for keeping skin dry and helping to prevent rashes.

How do pigeons always find their way home?
The species of pigeon have navigational prowess. Pigeons can find their way home, even if released from a distant location blindfolded. They can navigate by sensing the earth’s magnetic fields, and perhaps also by using sound and smell. They can also use cues based on the position of the sun. One theory is that they have both a built-in ‘compass’ and a ‘mapping’ ability. The compass keeps them flying in the right general direction and mapping lets them compare where they are to where they want to go, which is home.
It’s also thought the ‘compass’ relies on the angle and position of the sun. But how they actually ‘map’ isn’t understood.
The compass mechanism appears to rely on a combination of sun position and possibly iron ferite particles in the brain and trigeminal nerve and in a special organ on the top of the beak.
The map mechanism may relate to advanced spatial mapping and interpolation in the brain, possibly assessing and mapping atmospheric odors, magnetic variations, visual landmarks and low-frequency infrasound.
Studies of factors that disrupt homing show that all of these mechanisms are present but different breeds of homing pigeons use different sets of navigational cues.
Pigeons have a good memory of places they have flown before and always fly in a circle when first taking air, in order to mentally map these factors.
