Re: Forensics C
The best I've seen are plastic cups or some sort of glass container. I've used plastic bags and hated it, the team before is used the same bags and one had ripped open, spilling a powder over the other bags. This made it almost impossible to pull out the right powder without contamination...

Re: Forensics C
Also, I would suggest having a few alternative ID methods for powders just in case you don't get all the materials that are supposed to be provided, I've run into cases where we didn't even get a candle, let alone a Bunsen burner, so have other ways of identifying things like boric acid other than the flame test.

Re: Forensics C
Are you sure? The event sheet says the supervisor is required to provide a bunsen burner. Also I do know how to do identify that without a flame test anyway.

Re: Forensics C
Sometimes supervisors don't follow the rules. You'll be okay at States, though - Mr. Holdren always gives you Bunsen burners.spackenkillkid wrote:Are you sure?

I"ve been to an invitational where they used a technicality by stating that they had to provide bunsen burners, but they didn't have to light them.spackenkillkid wrote:Are you sure?

Re: Forensics C
A lot of the strikers they have at my school are worn out, so we brought a lighter.iwonder wrote:That's why I have a striker in the kit!

Re: Forensics C
Yep, always bring your own matches -- which are also good to use for fibers burn tests -- and/or lighter. I say matches/lighters but not strikers, because the former can also double as makeshift flame test equipment. Forensics at Stoga didn't have bunsen burners (idk why, because we were in a high school chem lab), so myself and a few other teams in the first block used the matches/lighters we'd brought as jury-rigged bunsen burners... until they said "no more fire" because the room had filled with smoke from an unrelated incident.darkwinters wrote:I"ve been to an invitational where they used a technicality by stating that they had to provide bunsen burners, but they didn't have to light them.spackenkillkid wrote:Are you sure?

Re: Forensics C
Does anyone know how to tell the difference between PC and PMMA polymers besides using the density test?
