Extended Schools Science Club enthused by their eruption investigation!

16th Oct 2024

Alongside, Mr. McEvoy, the children at the ES Science Club eagerly gathered around the experiment table, excited to see the results of their Coca-Cola and Mentos experiment.

As they dropped the Mentos into the bottle, the reaction was immediate—fizzy foam shot up in a geyser, drawing gasps and cheers.

Some took notes while others laughed, thrilled by the dramatic display of chemistry in action. It was a perfect mix of fun and learning, sparking their curiosity about the science behind the eruption and leaving them eager for more experiments.
