Our book suggested we do an experiment to see how lava flows over the land so we broke out our safety glasses and assembled our experiment. We took a small custard bowl and turned it upside down on a plate and then surrounded it with flour to make a little mountain.
Safe and fashionable
Then we melted about a 1/4 stick of butter in a sauce pan and poured it slowly on the bottom of the custard dish/top of our mountain.
It was very cool the way it cut rivers through the flour down the mountain just like lava does when a volcano erupts.
We let it sit for a couple of days so we could see the butter harden like the lava does into volcanic rock.
Very fun stuff!
