2. The Wonders of Baking Soda
Baking Soda has several purposes besides cooking!
If you put it in your refrigerator it helps eliminate bad smells. However, you need to replace it once the smell starts acting up again.
An even more useful aspect of Baking Soda is how it can extinguish grease fires.
Grease fires happen when you are cooking with oil and it gets so hot that it starts to boil. Then you'll see some smoke and then fire.
DO NOT PUT IT OUT WITH WATER!!
Oil and water do not mix, so the water does nothing and causes the oil to splash around when you pour the water, making the fire spread.
So what you do is pour Baking Soda on the fire. This will smother it, depriving it of the oxygen it needs to burn.
This is an even better reason to keep it in your fridge, easy access.
There are other uses of Baking Soda, but I find these to be the most important.
