Soda Fountains and Dog Biscuits…

I’m sure the world and his wife have seen the infamous Coke and Mentos experiments.
There are loads on the net but EepyBird.com host a few of my favourites, the preparation must have been huge!
We read a bit further and discovered that the reaction isn’t due to a chemical reaction between the soda and the mints. The fizzy explosion is caused by the bubbles of carbon dioxide gas in the soda collecting on the rough surface of the mints.
Anyway the Science Sisters, otherwise known as Freya and Erynn, wanted to try their own version and see if only certain brands of soda and mints worked or if value brands would work too.
Last night, while brushing their teeth, they were chatting about, “What else might work?”. After a rather hilarious rude list of suggestions of things with a rough texture, this is what we decided to try:
- Cola and Mints
- Lemonade and Mints
- Cola and Pebbles
- Cola and Raisins
- Cola and Dried Dog Food
What we found:
The mints and pebbles work well, though the pebbles get stuck in the tube, so don’t give such a big fountain.
Both the raisins and the dog food just float and so didn’t work.
The lemonade worked even better than the cola, we think this is because it looked really fizzy even before we started.
Enjoy the video – Excuse the wind, tartan blanket and choocter voice-over!
Mmmm…there’s also a strange pink glow radiating from Erynn’s head!
Next Time: I learnt something new today….
Blogging about our love of science, working from home & the experiment of parenthood!
Wow, I’ve never heard of this one! We’re going to try it though… Great vid.
Oh, and forgot to say, am highlighting your blog on BMB this week…
Thank you, better get writing some more posts…
If you want to try this experiment buy value brand cola (about 20p) as it’s super fizzy and the kids want to repeat it again and again!
Fab vid. will try this one sunny day
Yes, certainly one for outside only, a customers son, did this experiment in the kitchen on Hogmanay, glad it wasn’t my house!
Love it! This is brilliant. Would love to give it a go. I don’t think ‘the world and his wife’ know about this stuff so thank you for showing an ignoramus like me! x
You are welcome, “Egg in a Bottle” coming soon, hope you enjoy that too!
Wow, Fab!! I can’t wait to practice these with my 2. There are a tad too young at the moment, but your website is a wealth of entertainment on school holidays
Thank you – will be posting some topics soon that will appeal to younger children – dinosaur fossils, bubble making & slime recipes coming up!
Found this via the BMB carnival.
Brilliant! What a great mum you are making learning such fun!
Thank you

Ohh that looks like so much fun. I am expecting my first baby in July and look forward to doing great stuff like this with him when he is older. I do remember doing something similar with a bottle of beer and smarties when I was in college but that was the grown up version!
Sounds like you had more fun studying at college that I did!
thanks for this and the link! we are always on the lookout for science support round here!
No problem, hope you enjoy the blog!
