Now imagine the fun you could have if you could set those off at will while sat in a wheel barrow, office chair, bathtub in front of the camera.

That is a very funny thought. If the police wern't already looking for me for some other unpaid fines I'd do it just for the picture.

Just one question however....What is a dustbin lid? Is it just a flat peice of metal like i have pictured in my head?
