invention challenge!?!

I was on the tram the other day, and a young woman was rummaging around in her bag, and I thought – wouldn’t it be great if everytime you opened your bag, a light came on inside, bit like when the fridge door opens?
So, I then thought, how about setting the challenge to the Lab_13s who might be interested, to invent and design a bag that has a zip or some other fastening, with a series of LEDs on the inside that come on when the bag is opened…
there are 3 problems (at least) to solve –
1 a switching mechanism, that works when the bag is opened;
2 where to put the LEDs and batteries;
3 how to make sure that the lining of the bag is strong enough and doesn’t fray.

Prize for the best design?
