I had always wanted to make a big volcano for my son to play with. No matter how many times we try it, the vinegar-baking soda reaction never fails to amaze us.
We have tried a few variations and I decided to make a lasting volcano (which we can keep for a few months at least) for his dinosaur themed birthday party last may. Sure the volcano was a huge hit at the party and until we were ready to make it erupt, we used it as a centrepiece.
And it is still around after 7 months and I’m sure we’ll keep it a few more months. I’ve made a video about how to make one using papier mache (if you are new to papier mache, believe me, it can get really really strong and lasting). Hope you enjoy watching it and try it yourself.
To make your volcano erupt (basic method):
What you need:
- Baking Soda
- Red/Orange Food Colouring (optional)
- Glitter (optional)
- Dry Ice (optional)
Add vinegar to baking soda with food colouring though it works well the other way too. It’s amazing when the kids add the colourless liquid and see the magic instantly. It’s a good idea to fill baking soda, glitter and food colouring in the volcano beforehand, when the kids are not looking. Our bunch of party kids went mad when they saw the eruption after my son poured what they first thought was water.
If you have access to dry ice, add a bit of it before adding vinegar. I couldn’t get any while preparing for the party but it creates a smokey effect and adds to the fun.
