Vegemite bombs?

[Kyt]

I was reading this article, nothing special, except the following caught my eye:

Anyways, then WWII started and Australian troops discovered Vegemite was highly flammable and if treated correctly and stuffed into empty artillery shell casings, it could be hurled at the enemy, much like a grenade.

Errrr, riiiiight Well I can't find anything else on this. Anyone else heard of it?

Um, yeah, right. Great stuff though, magnificent on toast and adds a little extra to poached eggs on toast!

Mmmm not to my taste. The grenade sounds like better use!!!
