I've heard these 'facts' before.
- Glass is a super-cooled liquid. - amorphous vs crystalline vs liquids
- Plastic water bottles release dioxins when frozen. - Ok, I hadn't heard this one. I'd heard about leeching at high temps.
- Stainless steel is non-magnetic. - Some are, some aren't. Ferrite and martensite are magnetic...austenite are non-magnetic. Most (but not all) stainless steels are austenite.
- Spider silk is stronger than steel. - interesting discussion of 'strength' and 'toughness'
- Radioactive metals glow green. - I knew this one...though some do glow blue
