點解喺實驗室唔可以睡覺！！！（（20點

Why we can't sleep in the laboratory???
It is because there are a lot of toxic materials stacking up on the shelf and that'll cause harmful effects to anyone staying there overnight; also there is not enough room for accommodating such sleeping facilities. Finally, there is no washroom or other facilities provided for anyone to stay overnight there.
