Well, you have to stir it at such speed that isn't produce a lot of splashes and sprinkles in the flask. Ofc stirring is very important.

Yea, I was speaking my magnetic stirrer. On top stirrer would be great to purchase. But thanks! If I do this some wonderful day, I will stirr it "medium"... I have to say, within a year, I have laser thermometer, digital screen in my new stirrer with temp. and stirr speed screens. And 0.0001 diamond scale, plus many many more. First I have to figure out, how simple Leuckart reaction can go wrong with just P2P and formamide. I'm so frustrated.
