This morning we made fossils...

The kids made their own fossils. Logan's are impressions from
his Thunderbird rockets. Delenn made dinosaur tracks and
impressions of a beetle, dragonfly and fly.

The recipe is pretty easy, this is what we did:

2-3 Tablespoons used coffee grounds
2/3 cup salt (a little less)
2/3 cup flour
enough cold coffee to make the mixture dough-like

Make your impressions and then bake in a low heated oven
for a while (an hour on one side, an hour on the other).
