Our tongues play a huge role in determining the flavors of the foods we eat... But, they might not play as big a role as you think. Believe it or not, our tongues only do 20% of the work. Researchers have estimated that approximately 80% of what we interpret as taste actually comes from smell.
In this experiment, we're going to see just how important our sense of smell is to experiencing taste. As crazy as it seems, we'll bet that without your sense of smell, you won't be able to tell slices of apple, potato, and onion apart! This experiment requires the help of an adult. Never handle knives or sharp objects without adult supervision.
Hmm... it seems nobody's added a conclusion for this experiment yet. You can suggest one here.
