River experiment

My groups first idea was to make a kind of geiser to start the river. so we hooked up a rubber tube to the faucet ad buried the end in the diatomaceous earth and covered it then turn on the faucet. wen the water broke through it immediately started to make the river. it also worked in the sand and took longer to work in the rocks. our second idea was to make a little lake on top of a mound of diatomaceous earth to see if it would form a river when it over filled. this one worked only in the diatomaceous earth and kinda just got soaked up by the sand and pebbles. ummm yay i suppose.
