*Phew*...I'm glad to hear you've got the whole husk! Now for the bentonite...it's best to use liquid bentonite, but I guess it's not readily available in some places. Powdered Bentonite is fine, but you should hydrate it yourself before using it. Here is a link to a great site on bentonite:
If you go to the very bottom of the page you can click on a link that will give you instructions for how to prepare it. The liquid bentonites that I have used have had the consistency of thin yogurt...just thin enough to be pourable. Once you hydrate it just use a tablespoon of that in your shake.
Still confused?...just ask more questions if you are! ; )
