**Essay Goes Here.**
My science fair project is about can you taste 4 different sodas while holding your nose. They're four things that are important in my project is the four sodas which is Sunkist, Mountain Dew, Coke, and Root Beer.Now you are probably wondering what is taste? People say there is 4 different types of tastes, but I found a website which told me there is at least six types of tastes. You probably heard of the four basic tastes which is sweet, sour, bitter, and salty. Actually there two more which is fat, and umami. Umami describes as brothy or savory taste. (Taste and Smell)

Do you know why you cant taste anything when you have a cold? Well, when you have a cold you get congested ( stuffed up nose) this causes the air to stop flowing through and out the nose this is called **O****lfactory Receptors**.Which means the **Odor compounds** cant reach them and your smell doesn't work ( Taste and Smell). For example, lets just say you have a cold and you're eating an apple. When you bite in it you taste nothing. This means the **Odor compounds** cant reach the **Olfactory Receptors** so your smell does not work.

(About ScentSational Technologies) I learned is that there is a certain spot where the taste buds are. For example, bitter is located at the back of the tongue, sour is located on the sides of the tongue, and sweet is located on the tip of the tongue. Now it doesn't show where the salty part is but I think its located in the middle of the tongue because all of the spots are taken by the others. For some reason (Taste and Smell) shows me its wrong. He says its a myth and the taste buds are located everywhere.Which one should i believe?

Now (Wikipedia) told me its true it gave me a tongue map, and they labeled it for me
