Really, mine wasn't up to scratch, it was about a once-revolutionary female poet in 1805 bickering about how she's ended up in the majority to her child through a letter.
The emulsion our class did was making mayonaisse. I remember it well coz me and my partner rocked everybody else...you have an egg, add a bit of salt, vinegar, then slowly add 100ml of canola oil...nobody else had the patience to do it properly, it was this liquid but ours was like real...
