ChaCha

A month or so ago I heard of this cool service where you could text any question or call in any question and it would be answered for you. At the time I couldn’t remember what it was called and couldn’t find it on NPR or Google; then I saw it again on CNN:
ChaCha. All you have to do is text/call your question to ChaCha (242242 or 1.800.2242242) and it will give you the answer. Here is one I asked it just to see what it would say. Q: “Why is the sky blue?” A: “A cloudless sky is blue because molecules in the air scatter blue light from the sun more htan they scatter red light” How cool is that!!
