The Mentos and Coke experiment was always my favourite science activity when I was a teacher. We would get the class outside, place a bottle of Coke on a picnic table and watch the children’s reaction as I dropped in a few Mento sweets.
I shall never forget the first time we tried out the experiment. At the time we didn’t have a garden. Although we were not convinced that the experiment would work we did decided to try it in the bath just in case the coke bottle fell over. Feeling confident that it wouldn’t work we emptied an entire packet of Mentos into the coke bottle. The coke erupted with such force that it hit the bathroom ceiling. I managed to shut the shower curtain before most of the coke fell back into the bathroom but we still managed to get soaked. From then on it became an annual experiment to showcase to my class.
However, each year we would do the experiment on the picnic table and every year I would have to spend ages afterwards cleaning up the sticky coke. For some reason it wasn’t until I wanted to show Adam the experiment that it even occurred to me to use the Tuff Spot. The Tuff Spot is ideal for containing the exploding coke and is easy to clean up afterwards.
For the Mentos And Coke Tuff Spot experiment you simply need Mentos, a bottle of Coke and a Tuff Spot! We have found that cheap economy coke works just as well as the expensive brands. However, we have never found a cheaper alternative to the Mentos.
Position your coke bottles in the Tuff Spot and remove their lids. Pop a couple of Mentos mints into the bottle and stand back. The gas released by the sweets pushes all of the liquid up and out of the bottle in a huge eruption.
Adam was convinced that the eruption would make a loud noise hence he wanted to cover his ears. Next we let Adam try the experiment himself:
If you want your eruptions to go higher then replace the Coke with either Diet Coke or Coke Zero. The Mentos and Coke Tuff Spot experiment is a brilliant activity that is easy and quick to set up, easy to clean thanks to the Tuff Spot and introduces children to the wow factor of science.
