The first time my kids and I did the egg-in-vinegar experiment, I was stunned. It felt like… magic.
Of course I knew it was science at work (the vinegar’s acid dissolving the calcium carbonate in the eggshell) but seeing that bouncy, rubbery egg for the first time was a shocking delight.
I’ve turned this experiment into a free, one-page printable with a wizardy theme, designed to pair perfectly with the Escape from the Sorcerer’s Spell Escape Room I’ll be releasing next week. You can use it as a stand-alone science activity, or as a fun add-on to the escape room adventure.
A few tips:
This activity takes about 48 hours, so plan ahead.
If you’re doing it as a group, you can either:
Send kids home with secure-lidded containers, or
Do it as a group demo and have a finished “rubber egg” ready to reveal.
While the egg sits in vinegar, stop and have kids observe the bubbles forming on the shell. Those are carbon dioxide bubbles—the proof that a chemical reaction is happening right before their eyes!
Want a free copy of the printable? Just subscribe to Your Library Vault, and you’ll get instant access to this experiment (and other fun treats!) inside the vault.
And don’t forget—next week I’ll be sharing the long-awaited Escape from the Sorcerer’s Spell Escape Room.
Stay curious,
Allison
