Last Problem
Is the following true or false?
You should not freeze water in plastic bottles, as it can release carcinogenic dioxins from the bottle into the water.
Answer:
False
This is a hoax that was circulated on the Internet a few years ago. Althought there are likely to be dioxins in plastic water bottles (and there is still some debate on that issue), freezing them is not known to cause a chemical release to occur.
