How do you beat level 2 on causality 3

There are 4 levels to causality 3.

Level 2 (Restaurant) - There are 8 victims.
There is a long prelude in which you have to wait and then do several things relatively quickly.
- Click the poison container on the preparing table in the kitchen (bottom), The busboy will take it to the dumbwaiter. Click the small red button to send it up. The waitress at the top will serve it to a diner, who will get sick and run to the restroom. You kill her by clicking the ornate wall sculpture.
- As the blue bird flies over to land on the antenna, click and hold on the side of the roof water tank just to the right and a small vent will open. Click the antenna to drop the bird into the exhaust fans, and his guts go all over, including into the water supply. The fan blade decapitates one diner. The other 2 diners run left onto the balcony with the waitress. Click the balcony support to drop all 3 onto the smoking busboy below.
- When the red water gets the dishwasher to call over the cook, click the pan to set fire to the kitchen. The cook and dishwasher run into the meat freezer. Click the thermometer over the door and they freeze to death.
