After scouring Pinterest for some cool and fun dinosaur activities, I came across this recipe at Growing a Jeweled Rose for some sizzling, fizzling dinosaur eggs. I had to try it!
The only change I made to the recipe was that Crystal added food colouring, but instead of that, I added some soil from our garden.
Here's the recipe:
500 grams of Bicarbonate of Soda/Baking Soda (found a box at Pick n Pay for R11)
3 tablespoons of soil (not essential)
About 2/3rds a cup of water
Small plastic dinosaurs (usually available in tubes from The Crazy Store)
White vinegar in a squirt bottle (for the hatching to happen)
Mix the bicarb and the sand and then slowly add water until the mixture can be molded. Place some of it into your cupped hand. Add a small dinosaur to the top of the mixture you have in your hand and then cover it with more of the mixture. You should be able to mold the egg fairly easily. If the mixture is too sloppy, you need to add more bicarb. I then used a large sized plastic egg to help me get nicely shaped eggs. I used only the one half, just to help shape the egg a bit. Let it dry for 24 hours.
When the eggs are dry, place them in the garden for the children to find. Give them a spray bottle with the vinegar in it and let them squirt away. That's when the sizzling, fizzling part happens. :)
This last picture looks quite authentic and gross, don't you think?
All in all a really successful activity. Little One had a friend over to play for the day and after this activity, she told me that she wasn't ever going home. Hehe :)
