Strap-on duck will keep you awake? So claims the Argentinian inventors of the Duckmaster.
They say the Duckmaster is more than just a way for students to stay awake in class but also could be useful in keeping drivers from falling asleep at the wheel. How does it work? The Duckmaster fastens around the user's neck and starts quacking if the owner's head slumps forward. A good deal at £7.
I wonder how many student books will have this product in it. Seems like it would be perfect fodder for them.
