Paraffin Test

We observed a Paraffin Test last Friday. A Paraffin test is use to determine the presence of gun powder in the hands of someone who is suspected of firing a gun. The test is painful because the wax that will be put on your hands is hot but it won't burn your skin. You will just avoid touching water for ten to fifteen hours. The test wasn't finish yet because a reagent will still be drop to determine the presence of gun powder and our supervisor will do it next week.
