  • Trivia

    • In the classroom scene, there is a scientific inaccuracy where Olivia is performing an experiment to illustrate how lava is made. The ingredients she says she is using are water and what she refers to as "bicarbonate". Sodium bicarbonate mixed with water does not cause the foaming reaction that is depicted in the scene. To create that reaction with bicarbonate, the experiment requires an acid, which when combined with the bicarbonate base, neutralize each other and form carbon dioxide bubbles. Also, while some carbon dioxide may escape from volcanoes, the cause of a real volcanic eruption is quite different, despite Olivia's claim that the same reaction causes volcanic activity.
