I want to do the plastic milk experiment with dd2...

[lucysmam]

The page I've been reading says I need "non-homogenised milk". Would this be blue top? I've googled & it says the fat molecules are left in their natural state so I presume it would but am not sure 🤷‍♀️

Thanks in advance :)

Gold top

Only nonnhomogenised milk I know of is some Jersey milk. (Gold top) check the label though as some are homogenised (it will say which it is pretty clearly imo. Non homogenised is also used for cheese making!

Or silver top, gold top just has higher fat.

Ooh, thank you! I'm glad I asked now, I'm not sure anywhere round here sells gold top!

Homogenisation is the process by which the fat globules are distributed evenly and stay like that. In the olden days (1970s) most milk was not homigenised, only red top which was horrible. The difference between silver and gold top was the type of milk not the processing. Now more people have skimmed or semiskimmed and cream is cheaper, it used to be a luxury now it is a by-product.

I think the plastic milk thing relies on casein, so wouldn't normal skimmed milk work? Full fat homogenised milk involves the fat binding with the casein, but in skimmed milk they would have removed the cream first so the casein would still be free and therefore make the experiment work?

If you wanted op you could always get blue, green and red milk and do a double experiment by seeing what works best?

What's the plastic milk experiment? Sounds intriguing.

Any experiments I've googled just now just mention milk rather than non homogenised milk. Maybe try it with different types and see if the results differ. Non homogenised would have a layer on the top like you used to get from glass milk bottles

Waitrose organic duchy brand milk is non-homogenised

Thank you all, I'll go back and look again at a couple of different pages tonight, that was the first one I clicked.

@Gladioli23 that's a good idea to try red, blue, and green to see which works best! It'll take us longer too which is always a win when they're mooching with not much to do.
