The funny thing is I can't even go a day without a cup of coffee or some types of energy drink. What you said about "liquid to solid" is something that I find very interesting. For example, I think it is very interesting how a solid gold or silver bar can turn into liquid if you heat it up to the right temperature. If I understand this matter correctly, when the gold bar is in the solid form, its molecules are bonded (tightly) together. Also, as a pharmacy technician, you're surrounded with chemistry. Medication can save lives, but if one uses in the wrong way, it can does a lot of warm too.
