Jakob has a little toy that's basically a metal board with lots of magnetic letters and numbers.
So I tried to spell out "PUT SMARTIES TUBES ON CATS LEGS MAKE THEM WALK LIKE A ROBOT".
Didn't work, though, 'cos there weren't enough letters. Or rather, there were loads, but not enough of the right letters. I could only find two "T"s and one "B", so I only got as far as completing the first two words.
Still, I tried.
And apparently there are loads more letters at my sister's house, so, you never know...
