Cola vs Mentos Series #6 (FINALE)!
Testing cold (fridge), room temp & hot (boiling water bowl).
The science: Cold holds more CO2 but releases slower. Hot has less CO2 but releases faster. Which effect wins?
The height difference was genuinely shocking! Final video - which was your favourite?...

Cola vs Mentos Series #4: Rainbow Fanta explosion! 🌈
Testing 4 Fanta colours, including mystery purple.
The science: Fanta's carbonated like cola, so the same reaction! The colours don't change chemistry - just make it way more spectacular to watch.
Less about results, more about creating...

Cola vs Mentos Series #3: Do clear drinks work? 💧
Testing Sprite, sparkling water & Schweppes vs Diet Coke.
The science: It's not about colour - it's about CO2! Mentos create nucleation sites in ANY carbonated drink.
Sparkling water = cheaper + way less sticky cleanup! Pro tip for parents...

Cola vs Mentos Series #1: Testing 0.5L to 2L bottles 🚀
The science: Mentos' rough surface creates nucleation sites for rapid CO2 release. More liquid = more CO2 = bigger explosion potential.
The difference between the smallest and the largest? Massive!

Visited Wonderlab at the @sciencemuseum.org.uk with the kids — genuinely one of the best hands-on spaces in London for ages 7–14.
You can easily spend a couple of hours here: slides, friction stations, light tables, building challenges.
It feels like play, but teaches real science...
