Chemistry Song

Chemistry Wonderland Gases explode, are you listenin' 
In your rest tube, silver glistens 
A beautiful sight, we're happy tonight 
Walking in a chemistry wonderland.
Gone away, is the buoyancy
Here to stay, is the density
A beautiful sight, we're happy tonight
Walking in a chemistry wonderland.
In the beaker we will make lead carbonate and decide if what's left is nitrate
My partner asks "Do we measure it in moles or grams?" and I'll say, "Does it matter in the end?"
Later on, as we calculate the amount, of our nitrate
We'll face unafraid, the precipitates that we made walking in a chemistry wonderland. 

Send in the Clowns Biology

To the tune of "Send in the Clowns"
So this is it, A few bases to go, I've tried and I've tried but the techniques's so slow. I've poured my gels, I've run quite a few. Full of bubbles, they leaked and why I never knew. But where are the clones? I've got to have clones, The end is so near. Is my broth rich? Does it look clear? Contamination is something I always fear. Are my plaques blue? They shouldnt be, No DNA left I'm down on my knees, So give me some clones? I've got to have clones, The end is so near. I've had bad preps, There've been quite a few, Ive tried all brands of PEG, fresh buffers, but nothing would do. And though they say, Solutions will keep, In my hands they last no more than a week. So send me some clones? I've got to have clones, The end is so near. I've read my gels, My eyes are quite sore, There's still sequence missing, of this I am sure. But there it is!! Finally done. I've conquered this fragment and now I have won. Whats's this I hear? A voice from the door. My supervisor wants 10kb more! So give me some clones, I've got to have clones, Or I'll be here all year!
