Orange+Cup

Jess and I tested the residue in the orange cup. We were able to do this test by putting some distilled water in the cup and taking the water out and using that in our spot plate. We ran the tests for opiates, stimulants, coca alkaloids, depressants, halucinogens, and asprin, tyenol, and ibuprofen. At first we didnt get a reaction, but after a few minutes it reacted with the depressants. SOOO, we decided that the remnants in the orange cup is from a depressant.

I am Kierra Knight.I have had some forensics training for 8 months. I assisted Jess in testing the number 11 bag. She assisted me in testing the orange cup residue. We tested the orange cup on March 14th during first hour at approximately 8 in the morning. We did our test at one of the lab tables in the classroom. Because the cup only provided residue we had to add a little bit of water to the orange cup. then we ran our tests. We ran the tests for Opiates, stimulants, coca, depressants, halucingens, and asprin, tyenol, and ibuprofen. After adding the water to the orange cup, we took a little bit of it and put it in the spot plate and added a little bit of the reagents. After waiting for a little while we got a reaction for depressants. We had to wash our our spot plate in between tests to make sure we didnt cross contaminate any of our results. We also had to makes sure our table area was clean just in case we accidentally picked up any other substances on ourselves. Its just safer to keep our workspace clean. We were kind of worried at first because nothing reacted. But then it started turning violet which means it was positive for depressants.
