P7/6 finished making their volcanoes and painted them to make them look realistic. We then completed the ‘mentos and diet coke’ challenge to make our volcanoes erupt!

A bottle of diet coke is full of carbon dioxide (the bubbles). The bubbles stay suspended in the liquid until the bottle is opened. When mentos are dropped into a bottle of diet coke, it forms lots and lots of bubbles on the surface of the cola. When all of this gas is released it forces the liquid up and out of the bottle in a giant whooshing eruption of sticky soda, just like a volcano does!

We do not recommend you try this at home without adult supervision!

Primary 7/6 were so excited to watch our volcanoes erupt! Have a look at our pictures to see what happened…
