No batteries required

The apprentice and rug rat mk2 had a plethora of presents from our wonderful friends and family which is why it seemed to yours truly that most of Christmas day and Boxing say was spent inserting batteries into various bits of plastic and pairing up various radio controllers with various toys and then calming dogs/cats/birds down after any number of radio control cars and drones added to the festive experience.

Which is why the apprentice and RRMK2 spent the best part of 2 hours constructing this marble maze which was .... wait for it .... amazing :) and oh so quiet....
