Snake Taste
Snakes smell using the tip of their tongue, and a forked tongue allows them to sense from which direction a smell is coming. Sensing from both sides of the head and following trails based on chemical cues.
The advantage to having a forked tongue is that more surface area is available for the chemicals to contact. The tongue is flicked out of the mouth regularly to sample the chemical environment. This form of chemical sampling allows these animals to sense non-volatile chemicals, which cannot be detected by simply using the olfactory system. This increased ability to sense chemicals has allowed for heightened abilities to identify prey, recognize kin, chose mates, locate shelters, follow trails, and more.
In humans, the sense of taste is very much attached to our sense of smell. This is proven, for example when you have a cold and your nose is stuffed up. It is very difficult to taste your food with a stuffy nose.
You can practice your sense of taste at your sit spot by "tasting the air". Open you mouth and suck in air through your mouth. You may or may not taste much in the air but it is the safest way to experiment with your sense of taste in nature. With more experience, and with adult expertise, you can consider sampling wild edible plants from around your sit spot and backyard. Easily identifiable plants like Dandelions are a great place to start. Please, always have adult supervision and expertise before sampling any wild plants and use a local edible and medicinal plants field guide as a resource to help identify wild edibles.
