Yeast Starter

Got my starter going last night. I boiled one pint of water with 3/4 cup of LME, cooled it to about 72 degrees and funneled it into a Pyrex flask, then pitched the yeast and added the fermentation lock. That was about 10 hours ago, no real activity as of yet. I plan to make the beer later tonight, and I'll post the recipe once I've got it going. Cheers!
