I went to a fancy restaurant on the weekend, complete with glass like plastic bowls. You know, the ones that look like glass, but…

Well, I’m 99 per cent sure it’s a plastic bowl. It just doesn’t quite shine like a glass bowl would, it’s a bit dull.

Also, I’m not sure it’s heavy enough to be glass. I would expect a glass bowl of this size to be a little heavier.

And it definitely doesn’t make the right sound when I tap on it. So, it must be a plastic bowl… I think.

I think it’s plastic, but how can I be sure? I could throw it on the ground. Yes of course! And just wait to make sure no one’s looking and…

SMASH! SHATTER! SMASH!

Umm, so the bowl was plastic… but that window definitely wasn’t.
