To start the process of taking apart and disposable camera is to use a screw driver and pull the sides apart. Them make sure to take the battery. Then the Film should come out. After that take out the little lense.
We took off the casing.
After that you should see a green box looking thing and on the sides of that you should be able to pull the green box and run your screwdriver across it a couple of times.
Lastly when taking the camera apart you should be able to take out small white clear parts that just help take the pictures
