On a beautiful sunny Monday morning, we made a volcano out of sand. It was really hard to get it to the right place. We added water to make our sand stable.
After that we put water,food coloring and baking soda in the test tube. We shook the test tube to mix them well. We put the test tube in the middle of the sand mountain. We got a cupful of vinegar from the
teacher. Then as we poured it slowly watched the red foam came out of the tube. It was so satisfying 1 second 2 second and the whistle blew. It was an overflow of red foam w hich we think was the lava from the volcano. What an amazing explosion. We were all excited and screamed with joy.
After that we went to go tip the rest of the sand out into the sandpit.Ten we went to rince all the sand out of our tray.
