Exploding pumpkins

Today in science we put yeast and water in a styrofoam cup then we put dish soap, peroxide and green food coloring in a styrofoam cup . Then we put the green goop in a pumpkin that we had carved ahead of time . When we poured the yeast and water into the green goop . It didn't work turn first time!   When we tried again, it did work, but very slowly, so we had to just pour it out to make it throw up. By:  Kassidy Langley
