Elephants Toothpaste

Today in reading we conducted the Elephants Toothpaste Experiment. The ingredients we used were: hydrogen peroxide, blue food colouring, dishwashing liquid, warm water and yeast. In my opinion it didn't really work because there was too big of an opening for the gasses to escape from. What is supposed to happen is that it makes a smooth foam that bubbles up and overfills. Ours was more like a liquid that just overflowed due to the fact that the glass couldn't hold any more liquid.
