Planet 51 juice

On friday our class had to make a Planet 51 drink.  It was so sour! It was the worst lemon juice I have ever tasted. It had too much baking soda in it and that is what it tasted like. Then we got into groups and made our own lemon juice. We put in 4 teaspoons of lemon juice and only 1 teaspoon of baking soda.  It was much better it tasted like lemon juice.
