Forensic scientists can determine if a bullet hole is an exit or entry thanks to the<u> appearance </u><u>of </u><u>glass surface.</u>
<h3>Bullet contact with glass</h3>
- When a bullet goes through glass, it would take more of the glass surface that it hits along with it.
- This leads to the front hole being smaller than the exit hole.
Looking at the glass surface will then allow the scientist to note where the bullet came from based on which hole is larger.
In conclusion, a glass surface helps.

<span>Alright.. this is what I have in mind... then you can judge if I'm totally crazy:
As in any other experiment we wish to only hold 1 variable, while other thinkable variables are held constant.
In addtion to that we need to ref. soil and call that 0.
Now some theory: We know from medicals they can have synergetic effect if mixed. Same can go for nutrients, we therefor test each soil mixed and alone and see the effect.
We call the nutrients A, B and C, (continue with more if you like)
Now this is our setups:
0, A, B, C, AB, AC, BC, ABC.
In this way we can make compare to a ref soil (0) and also check for synergetic effects... this is a bit considered a multivariable experiment, but we also have A, B and C as ref. against the mixed soils.</span>
I think it's the first one and the third one. Not completely sure though.
