Frankensnakes – an engineering-inspired Halloween trick

This post is sponsored by The Year of Engineering

You may remember Talitha tried one of the activities developed by the Year of Engineering’s Holiday Makers in the summer. They’re back again with more engineering-inspired activities for children aged 7-16 over the October half term. My kids always light up when they hear anything about engineering because one of their aunts is an engineer but the reality in this country is that only 12% of those working in engineering are women and only 8% come from ethnic minority backgrounds. The Holiday Makers are aiming to help families get making and inventing to discover what engineers do and find out why the field is a really exciting one to get into.

So we were asked to try out one of the Halloween-themed activities that The Holiday Makers have designed for October half term. The one we gave a go was called “Frankensnakes” and the idea was to make gummy snakes “come alive” using a simple chemical reaction like the ones engineers use to protect our environment and generate energy. Check out our three-minute video of the engineering-inspired Halloween trick.

We used baking soda and wine vinegar to make the gummy worms wriggle, which was both mesmerising to watch and raised questions about all of the different things involved in engineering. We found that the first set of worms we used didn’t move that much, despite being cut lengthways to make them lighter so we tried the experiment a second time with a smaller set and found it exciting to see what a difference it made. The chemical reaction forms carbon dioxide gas bubbles which float to the surface, pulling the worms with them and making them wriggle but clearly, factors like the size of the worms can affect the results. You can find out instructions for this activity and more about the science behind it on The Holiday Makers hub.

There’s so much fun stuff on The Holiday Makers website to get kids age 7-16 thinking about engineering and feed their curiosity As a parent of a child who loves to keep track of her progress, I found their Holiday journal a fun touch. You colour in sections to show how many of the activities and events you’ve been to and there‚Äôs another page at the back where you can write about your discoveries. The idea is that you can take it back to your class to share what you’ve been up to with them, or, in Talitha’s case, we can store in a folder for our own memories as she’s home educated.


The website also has lots of ideas for events across the country to help kids take a closer look at engineering. We love the look of the Fireworks and Fairgrounds event at Winchester Science Centre. With bonfire night coming up, it’s the perfect time to ask questions like “what gives fireworks their different colours?” and “why do they go whizz and bang?” There’s a lot on over the next couple of weeks so I highly recommend you take a look and find an engineering-inspired event near you.

For now, we’re just focused on working our way through the rest of The Holiday Makers Halloween themed activities like making green slime and causing ghastly ghosts to dance.
