I was looking at images of lava flows for an art project with the third grade students and I kept coming across a drink called a 'lava flow' http://gohawaii.about.com/od/drinks/r/lava_flow.htm
I thought that when persimmons came into season that we could make a non alcoholic version with persimmon puree. I used a combination of coconut milk, frozen bananas and purple sweet potato for the top or 'hot ash'. The bottom was just pureed hatchiya persimmons. Students used a straw to pull up the hot lava and then drank it. A lot of fun and a great connection from our garden and the third grade science unit.
