So they didn't accepty my idea of throwing bug/lizard/frog drawings into the Chilled Water Plant. even if I would collect them back. So I needed to come up with a solution. And I am not giving up on the idea of co-memorating the creatures who die in there. So My solution alternatives:
1. film the creatures in a bath tub, then insert it into a video of the water plant. either by 1. aftereffects 2. projecting onto the water
2. film the creature in a pond, a pool, or river and do the same as above.

So I need to experiment these things this weak. So if I make a list of things to do in priority:
1-draw creatures bugs by Thursday (DONE)
2-screen print creatures on Thursday
3- film the chilled water plant
OVER THE WEEKEND:
4-film the bugs
5-do after effects next week
I think it will work.
