chemicals in a science lab
Unless you know what chemicals you are mixing, and what kinds of chemical reactions they are going to have, you don't know what will happen when you mix chemicals. There are some chemicals which, when mixed, will release a very deadly poisonous gas. There are other chemicals which, when mixed, will explode or burst into flames. Even aside from that, chemicals in a science lab are there for some reason. Someone obtained those chemicals for the lab and intends to do something with them. They are not there to play around with at random.
You should never eat in a science lab because food particles can contaminate experiments, leading to inaccurate results or dangerous chemical reactions. Additionally, consuming food and drinks in a lab increases the risk of accidentally ingesting harmful substances.

If you eat in the lab, the food and the chemicals can mix and you might get infected... :( hope this helped you :)
