Science teacher makes rockets out of Diet Coke and liquid nitrogen

A science teacher has recorded a video that offers a new take on the whole Diet Coke/Mentos explosion phenomenon.

In this video, filmed in Australia this week, Jacob Strickling from the YouTube channel Make Science Fun builds a rocket out of the fizzy drink and liquid nitrogen.

He explained how it works online: "Instead of adding Mentos to the Diet Coke, add some liquid nitrogen instead.

"Then quickly turn the bottle upside down and wooossssshhhhh!"

"As the liquid nitrogen boils and turns to a gas, the expanding gases force the Diet Coke out the bottom in a frothy high velocity eruption, which in turn makes the bottle take off like a rocket (Newtons Third Law)," he continued.
