Caution should be exercised if heating directly in a flask. For more information refer to the "Can I boil directly in a flask?" question in the Hints / FAQ section of our Making a Yeast Starter guide.
Ensure that the flask has a flat bottom otherwise it is more likely that the stir bar will not spin properly.
Hint: When you're done making a starter and want to get the stir bar out for a second starter or before you pitch, use a rare earth magnet on the outside of the flask to pull it up the side. While there's no harm in accidentally dumping the stir bar into the fermenter (we've all done it), you will inadvertently forget it's in there and end up pouring it down the drain when you go to clean the fermenter. That's why it's always good to have spares. ;)
