This is an idea for a simple gadget designed to appeal to parents of teenage children. The get-up grenade is the size and shape of a small ball and can be charged either by connecting to a transformer or by winding-up an internal spring. Once armed in this way it is triggered by pressing a small button flush with the surface
When the time comes to get ready for school, the busy parent simply opens the teenager's bedroom door and tosses in a get-up grenade - preferably rolling it under the bed or similar, awkward location. After a short delay (5 seconds seems about right) the grenade goes off with a loud, high-pitched sound which can be stopped by a second press of the button.
For parents with several children, we envisage the product being offered as a set of five, together with an attractive, purpose-made bandolier.
This idea may be freely exploited without restriction (see earlier posting)
