its important to note though that there is no mystery or chemical nastiness behind the transparency effect - it's just changing the refractive index of water!

I am very fortunate to be able to do stuff that I like, but I also aspire to be useful. It pains me that I am not reaching that standard yet, I will think more about how to improve.

I really want to figure out if my extractor fan is actually doing anything good.

I didn't know about the Maillard reaction, and this is good info. Thank you, and I'll do this for next time. I want to figure out an easy way to make PM2.5 to test my air purifier.

Thanks for your suggestion. I did use oil here, but not alot. I should measure it next time. I'm trying to figure out how to synthetically generate uniform particles for testing some DIY filters I'm making, and just frying stuff in more and more oil seems like a good bet.
