Chemical or fizzical?

Want to create a cola explosion?

Do it Yourself - THE EXPERIMENT!

What you need:

  • One large bottle of diet cola (diet is better than regular cola because it has the most carbon dioxide gas dissolved in it)
  • Mentos
  • Outdoor open area
  • Protective clothing

What to do:

  1. Wearing your protective clothing set up the cola bottle on a flat surface in an outdoor open area
  2. Drop mento in the cola bottle
  3. Watch a cola volcano erupt in front of you eyes!

Why not personalise your experiment. You could design and perform an experiment to find out how much carbon dioxide is dissolved in a fizzy drink. Try to discover a better bottle of fizz with more dissolved carbon dioxide.

Are there more effective 'nudgers' than mentos? Try and come up with things that look smooth on a large scale but would be very rough and pointy on a microscopic scale. You could discover the ultra mento!
