This is a gallium and aluminium alloy spoon which reacts with water. Aluminium is a reactive metal, so it easily reacts with water. However, the oxide layer on a normal spoon prevents this from happening. When alloying aluminum with gallium, this aluminium oxide layer can’t form.

oh god I wish I had asked someone this when I was in high school so this might be long, I’m sorry

OK SO

My favorite subjects were by far forensic anthropology, literature, criminal justice, and criminological theory. I also had non-required classes that I ADORED like forensic psychology, cold case studies, blood spatter analysis, and ballistics.
My least favorites were definitely intro to forensics, chemistry, biophysics, and forensic chemistry. However, 99% of this was due to the fact that the curriculum and workload sucked, and I hated the forensics department chair with a passion and a vengeance. That man managed to suck the joy right out of everything-a bad professor can ruin a subject or course for you, so never be afraid to switch professors or courses if you’re having a hard time with them! I didn’t do this and as a result, a lot of these classes plain SUCKED for me. While I often understood the material really well, my performance wasn’t great and I never connected with the professors.
The easiest classes were the ones I enjoyed, but the hardest ones were by far chemistry and anatomy due to the sheer volume of information you’re expected to take in and memorize. I have ADHD and thus a shitty memory, so this was not a good combination.

Study Tips:

So I never really learned to study in high school and didn’t figure out what worked for me until like year three of college, so this is what helped me the most:

  • My notes in class were disorganized and scrawled at the speed of light trying to keep up with the teacher, so at some point after class (usually a day later) I would have a separate notebook where I would carefully copy my class notes. I would go slow, make sure it looked neat and legible, and to make it fun I would color code them or use glitter pens. I would also go back and include examples or practice problems that weren’t in my original notes-this and the act of copying itself made me more likely to remember things.
  • Flash cards are good for simple stuff (periodic table, word definitions) but for more complex concepts (parts of the brain, bones in the foot, etc.) I would draw out diagrams or print them out online and label them. And I would do it again. And again. And again. First from textbook, then eventually, from memory. I’m a very tactile person so the more often I did something with my hands, the more likely I was to remember it later-this was super useful in anatomy class.
  • Get a tutor! I had SUCH a hard time getting over my anxiety to even contact one cause I was so worried about looking dumb, but once I did I started doing so much better in my classes. I went from a D- to a B+ in chemistry II over the course of a semester because I finally gave in and saw a tutor. No one’s gonna think you’re stupid, and oftentimes tutors are great for just having someone to hold you accountable and make sure you get in at least an hour of study time a week.
  • For tests: as soon as you receive your test, write down every formula, fact, equation, or tidbit you can remember. Now you have a reference sheet for all of that stuff and you don’t have to spend the test stressing trying to remember what formula to use.
  • This is weird but don’t study on your bed. Or do homework on your bed. I did this all the time and it confuses the hell out of your brain-you can’t sleep well in bed cause now it’s The Work Place, but you have a hard time working anywhere else cause it’s The Work Place. (I didn’t actually stop doing this until very recently, and I can confirm the change was drastic.)

    Anyways sorry this was so long, I hope it was helpful! If you have any other questions, don’t hesitate to ask-I wish I could go back and tell my younger self all this stuff. Best of luck, future forensics major! We need more of you!

i thought i’d do a little intro now that i’m coming back to this blog!

about me:

  • Rhea Jay (my friends mostly call me Jay)
  • 23
  • she/her
  • bachelor’s in Chemistry and Environmental Science
  • I will be a first year grad student in the fall studying Environmental Chemistry
  • I was a track and field athlete in university (since I was 9yo actually which seems so crazy honestly) so I’m trying to keep active now that i’ve graduated
  • I like painting in my free time though i’m not very good
  • i’m studying Korean at the moment, but i studied Spanish throughout my schooling
  • i am a huge sims 4 fan and play nearly everyday

i think that’s about it. I’m so excited to be reviving this account for grad school! ✨ also here are some blogs i love: @choliestudies @cafe-study @emmastudies @coffeeandpies

So sulfuric acid is one of the six or seven really strong acids, and while not all strong acids are corrosive, this one definitely is. When sulfuric acid comes into contact with organic tissue, it begins corroding the tissue immediately, causing rapid onset necrosis. This is especially deadly if the acid’s fumes are directly inhaled, as contact with the trachea or lungs will cause severe damage. However, that being said, the primary cause of death when one comes into contact with this substance is circulatory shock, when the body for whatever reason cannot maintain proper circulation and organ function. (Oftentimes this is just referred to as shock, since there are many different causes).

A lethal amount of sulfuric acid is anywhere from one teaspoon to half an ounce. If this amount or more were to be directly injected into a vein, it would cause a very rapid yet painful death from circulatory shock. As soon as the acid enters the body, it will corrode any blood or tissue it touches, causing widespread necrosis and hemorrhaging as the heart pumps blood through the body. It would be exceedingly painful, but death would likely occur within a matter of minutes due to either the large amount of internal hemorrhaging or the tissues of the heart and lungs being corroded. However, given that this stuff will start killing your tissues the moment it comes into contact with you, you’d probably pass out from pain and blood loss in less than a minute and be dead a couple minutes later (by my estimate).

Because of everything that has been going on in the world lately, I took a bit of a social media hiatus to help clear my head and center myself. I’m feeling much better now and I have returned with news: I got into my number 1 graduate program! I am so beyond excited to start school again in the fall and document it all here.
