causing disorder around the school
prevent movement by causing too much noise it causes disorder
.
it will send signal whenever some1 try to tilt or movement .

Are u still sticking on this idea? If yes, just do a model chair
size of kiddo chair. put sensor touching the ground on all four
legs and also at the buttock =).
When the buttock sensor detected an ass, it will switch on the
four sensor on the chair leg. When any sensor loss touch with
earth, it will beep loudly. Hence, informing the teacher that
someone is not sitting still.
When the buttock sensor detect nothing, it will off all other
sensor and allow the chair to be carried into other location
without beeping.
I think A1 liao! haha...
