A fun afternoon at the office. David was boasting about his pen (it's a Space Pen) and claimed that, as well as writing upside down, and underwater, it can write on butter. Yes, butter.
Well, I'd bought butter that day, so I chilled it down in the freezer.
David got out his pen, and ... well, what do you know, it doesn't work! It made some nice dents in my block of butter though.
For the record, we tried a much more plausible scenario after that, writing on greasy paper. Which, as you know, works really badly with most pens. Well, the Space Pen writes beautifully on greasy paper, and keeps writing after that. So it IS an impressive pen. But I'll have to work out some other way to write notes on my butter.
