This pose allows you to put a Sim inside the container that comes with the "Get to work" expansion pack. This item can be found in the basement of the laboratory, or in build mode as "S1M5-4 Test Tube Pedestal".
It's just one pose.
The pose has a slight animation that helps enhance the effect.
This file doesn't add any new interactions to the object, although that would be cool :'D It also does not include the object itself.
