Fun fact, my VFX teacher actually worked on Flubber, and I'm pretty sure he would 100% agree with all of this. He at one point worked about 16 hours on a 3 second scene of a car alarm going off while Flubber flew by. Funny thing is, the thing he worked 16 hours on was the car alarm and the effects surrounding it, not the 3D jello thing. He suggested it that the car lights blink while Flubber flies by and they wanted it. He spent 16 hours just adding in the lights around the car just right, and you look at the scene for maybe 3 seconds. He's super proud of the work he did on it and rightfully so. VFX artists don't get the credit they should, but I feel they shouldn't or else the reality behind it will be unraveled to the audience.
