Our volcanoes bubbled and erupted!
The children throughly enjoyed setting off our volcanoes. We compared baking soda and vingear to mentos and diet coke. We didn't get quite the whoosh we were expecting from the mentos but it still bubbled happily. Furthermore, this gave us an opportunity to theorise about why it didn't whoosh. We did enjoy a video where the experiment goes WHOOSH! We wonder if we needed a tube with all the mentos being released at once (for that dramatic effect)! Check out more photographs below to see what happened and the powdery after effects!
