Today's science lab was the second half of last week's lab, and arguably the more fun one. Each table was given a bird's feather, and drops of oil would be placed on the feather. This was supposed to be a bit like a bird caught in an oil slick. The goal was to get the feather clean without ruining the feather, as this would kill the bird. Now, what did I learn from this? Cheap liquid soap spreads around oil, vinegar only fizzles a bit, and baby shampoo may smell nice, but is otherwise useless. The other thing I learned? Baby powder is probably the worst thing to use in this kind of situation, as all it does is crust onto the feather and ruin it. And it's also pretty funny when it happens to other people, and it isn't an actual bird. Oh, and the last thing I learned? Pet shampoo and... Citric acid, I believe? Anyway, they're the best combination for clearing away the oil, which Ms. Martinez told us after the lab was done.
In conclusion, it's now very clear to me why sixth graders don't handle animals from oil slicks.
