Summary

A pair of measuring cups on a stick.
Coose yor volumes.

Originally made for measuring cornstarch for oogoo rubber.
But equally good for coffee powder or anything else.

Instructions

Eiter use the common decimal fractions (in cubic mm):
An example sequence:
(100,500);-(200,1k)-;-(500,2k)-;-(1k,5k)-;(2k,10k);(5k,20k)

Or use powers of three.
With those you need the least number of measuring cups but calculating exact volumes gets cumbersome. Good for ratios though.
A suggested base size sequence in cubic mm:
(10,30);(90,270); -(810,2430)- ;(7290,21870)
Or maybe better:
(30,90); (270,810) ; -(2430,7290)-

Better make the stick a little too long than a little too short.
