Ultimate Domino Stander-Upper

This is the best invention ever, if you like standing dominos up and knocking them down. My daughter bought it from 'The Works' for Lexi when she came to collect her.
It is miraculous. The dominoes are collected easily (ingeniously) in the long tower and then you clip it into the train, turn it on and of it goes standing one domino up after another until it runs out and you fill it back up again. See extra for an advanced shot of it. We've never had so much fun :-).
