Frequently Asked Questions
1. Can I use other types of vinegar?
Yes, apple cider vinegar or white vinegar will work, but white vinegar produces the best reaction.
2. What if my eggs crumble?
Ensure that the mixture is tightly packed in the molds and fully dried before removing. You can also try adding a touch more cornstarch to stabilize it.
3. Can the eggs be stored after making?
Yes! Keep them in a cool, dry place in a sealed container. They’ll last for several weeks.
4. What type of toy dinosaurs work best?
Small plastic dinosaurs that can easily fit inside the molds are ideal. Look for figures that are durable to withstand the egg crumbling.
Suggestions
- Pair this craft with a "dinosaur dig" activity afterwards.
- Create a themed party around dinosaurs, using these eggs as favors.
- Host a mini science day where kids can learn about fossils and paleontology.
