student: "yes, actually there are two types of silk."
"really? okay, which one of the types do you think this is painted on?"
student: "well. the first type is spider silk. when spiders want to catch their food, they spin a web made of spider silk. then insects get stuck in the web. then the spider wraps up the insect in more spider silk before he eats it. spiders are arachnids, you know?"
"that's an awesome fact, but actually, this isn't spider silk."
