Diminishing milk - Multim in Parvo

An old but still excellent effect that fits every family magic show!

On the table are 4 (plastic) glasses. They are different in size. The magician fills the biggest cup and pour the cup completely full!
Then he pours the contents of the beaker in a smaller cup. To everyone's surprise, the milk may be just in the smaller glass. Whether there is now "solved" some of the milk?

Then, the magician pours the contents into a smaller cup, but now he has no milk left?

Finally, does he pour the contents into the smallest cup, this is 8x smaller than the original cup, but also now matches the content exactly ...

If desired, you can also do it the other way, ie where there is more milk to come.

Use a milkpichter if you want to work from big to small. The optical illusion is even better.
You can also use our miracle milk instead of real milk.
