is anyone else obsesed with this event? i love it. i love it. i love it. but one question i have to ask can anyone tell me how to do a GOOD chromatography? Even though I'm in C now i never got how to do a good one the pens eather mearged together (group chromo) or the pen bleed into the water (blue water) or the ink just kinda rose together in an ink blob i just want to know cus it prevented me from geting first oh well i still love my medal but it's a just beacuse i wanted to know moment..

I tried this event in 6th grade. Sucked at it.

i thinks theres alot of memory involed here with the reactions and what not anyone else agree/disagree?

Best event by far!!! I'm just wondering for B, does ayone else not like the piece of paper? Anyway, about the chromotography, a good way to do it is do have 1 inch wide pieces of paper, about 4-5 inchs tall, and then put a small,light dot so that it is not touching the water but is close. Then, fold the top of the paper over the side of the beaker so the bottem of the paper is in the water, BUT THE DOT IS NOT!! Then wait and take them out once all of the colors look pure. Also, make sure to mark the top of the paper with a pencil so you know which is which.

i did it last year but i was just a shadow. i dunno much. sorry

ya the paper kinda took the fun out of it. I''m kinda know for my memorisation of things all my events are alot of memory but it kinda took some of the fun out of it did anyone else use graph paper?

We used a piece of normal lined paper but we had tons of space left so we put on some info we would never use and didn't even look at the sheet at the competition.

i made a chart of cheatyness oh well i didnt look at it tho but i spent HOUR makeing it oh well

Last year it said in the rules you had to identify blood splatters. Does anyone know what that meant?

umm i think it had something to do with like where the blood was from (like from what hight and angle) but it never came up in any of my compitions ever but it shouldn't be that hard i mean the higher it's from the bigger the splatter and the more the angle the more one sided it would be (like imagine a cartoon sun with all those fake rays, and cut it in half something like that would of came from a sharp angle right?) but to be honest im not totally sure
