Location reference and unexpected issues

Reference:

Issues:
1.We did not come up with a solution to shot the scene that the phone drops into water (Without damaging the phone).
2.The effects that the pillow collects paper in the air is hard to reveal.

Technical issues: The video goes blur.
                             The lighting is not right(overexposure somehow).

Solution:



Technically:
 Sets the IOS to 400 and adjusts the lighting by using LED light and change the aperture.
 Moves the bed so that we can shot while the sunlight comes from the back of the camera
