For Science! The Coffee! Day 6!
September 12, 2007

Well, the excitement is over! It would appear that non-dairy creamer is the most effective growth medium clocking in as the first to grow mold. A tiny colony of visible stuff is starting to grow in the black coffee, but nothing more than a visible distortion so far. The milk has gelatinized and is quite not-scrumptious looking. I'll post pictures once stuff is big enough for the camera to capture.

A summary pic has been posted! It would seem that CoffeeMate is creepy stuff that nothing has grown in yet. Eeew.

For Science! The Coffee! Day 3!
September 09, 2007

Oooh, exciting! There are some results forming. The petri dish with the non-dairy creamer has began forming a little film about 38mm in diameter. It's not quite growth yet, but it's certainly a start - though, with this being the non-dairy creamer it's also possible that the creamer is separating out. We'll see soon!

For Science! The Coffee! Day 0!
September 06, 2007

So, my petri dishes came today. Oh the joys! This evening I brewed up a batch of my standard strength coffee to test just how long it takes to grow shit. Oh, but what fun would one dish of coffee be when I could have a whole set?! Well, I am currently testing:

• 50mL Coffee
• 25mL Coffee + 25mL CoffeeMate Creamer
• 25mL Coffee + 25mL Milk
• 50mLCoffee + 1 packet non-dairy creamer
• The brewed coffee grounds

What do you guys think is going to grow the fastest? I'm thinking that the brewed coffee grounds will get life before anything else (just from experience) followed closely by the CoffeeMate Creamer. Where's your guys' votes?

Ed 2007/09/07: I'm going to post update threads every two days or so. I really have no idea how long it will take to grow stuff on the coffee - but I think that every day will be too much.

Coffee + (sort of) Science == Fun!
August 29, 2007

So, I ordered some petri dishes yesterday. The great amazon informs me that they should be here sometime towards the end of the week, leaving my last free weekend before school to be spent in pursuit of something I've long wondered about - just how long does it take coffee to grow shit.

Sure, I've performed accidental experiments in the subject before - but the resolution on these has usually been only as precise as a few weeks and my level of revulsion at the growth in my coffee cup. This time, however, I'm actually going to be paying attention to this! Granted, I has no microscope so this will only be based on macroscopic growth... but it will be interesting to me none-the-less.

What will I test? I believe that I will test;

• At least three straight black brewed coffee
• One plain tap water
• One coffee w/ liquid creamer
• One coffee w/ powdered creamer
• One fancy coffee w/ liquid creamer and syrup
• One unbrewed 50/50 mixture of coffee grounds and tapwater
• Possibly some fresh-ground brewed black coffee as well

Sound like fun? I'm writing this now, because I'm interested in taking suggestions. If you have something (within reason) that you want me to put in these petri dishes - put it in the comments and I'll (probably) do it!

What's that Andy? :)

Oh... godamnit... just one more...
