Answer 1

That's a lot of questions!

1.  Don't set the lab on fire = keep flammables away from the flame.   Don't destroy your eyes = wear goggles.  Don't burn your hands = wear gloves.  Don't cause an explosion = be aware of whether you are heating something that should not be heated.

2.  IDK.  Sorry.

3.  Crashes when you are on it.  Crashes on top of you.  Alters the climate affecting all humans.  Carries sick people around the globe spreading disease.

4.  A theory does not become a law.  They are two different things.  This is like asking how does an automobile become a train?
