Doing pre lab practicals at late night...

I hate the fact that, for organic chemistry practical theres always like no time to complete the reactions. For example, during my previous caffeine extraction experiment, I could not even have enough time to weight the sample and record down my findings etc. 

I smuggled the sample back home somehow, even though I tossed it into the bin previously. It is still intact now.

Now I gotta complete all these pre lab works, man. Not saying that I hate practicals but I really hate writing down so many stuff after each practical s completed.
