Speaking of poisonous substances, when I was little we used to have a gallon container of "passion punch". You would mix a teaspoon full of the syrup into a glass of water and it would turn into a koolaid-like substance. I have always been amazed how it never ran out during my entire childhood. I just now realized it was not so much because it was so concentrated, but rather because the taste kept us from ever coming back for more unless we got really desperate. There are also positive examples of concentrated substances like frozen orange juice concentrate, vanilla extract, cleaners, and laundry detergent.
I appreciate the whole concentration concept and think it makes sense and is good for the environment, but I'm still a little skeptical about some product claims. Does the concentrated laundry detergent really go as far as it claims to? Is the nerve gas really as lethal as people claim it is? I guess I will never know. These are some of the mysteries of life that I may go down to my grave never solving. One of the reasons I try to live a good life is so when I die I can have access to the heaven library and get answers to all of my questions. Things like who killed JFK, UFO cover ups, conspiracy theories, and finding out who dropped off anonymous Christmas treats and gifts and our house.
PS- When I make frozen orange juice, it says to mix it with 3 cans of water. I like to add 3 and a half, because I still think it has plenty of flavor that way. If there are a line of thirsty kids waiting for me to make it, I will sometimes even bump it up to 4 to make it last longer. Please don't tell.
