I'm tutoring my 7yo nephew & he just won't agree with me that diamonds are made of a particular substance. Can someone please answers this question: What element are diamonds composed of? I'm not sure if he'll believe a few other people either, but it's worth a try.

I saw a Chinese man treat back pain on a patient using a paper towel soaked in "water" wrapped around a piece of aluminum foil. According to an IR-sensitive video camera, it showed massive heat being generated (202 deg. F) from the towel.
What other chemical or liquid could he may have used to generate this heat and attribute to chi?

I heard that the temperature of Pluto is around -380 F. This would instantly kill any human. Pluto is relatively close to a star (it orbits our sun) and gets its heat from that star. Therefore, how cold is it in deep space where no stars are nearby?
