How to make dino eggs with baking soda.

Make a DIY Toy Surprise with ARM & HAMMER™ Baking Soda! From the little dino egg, pop a toy inside and then, with a little vinegar, watch it dissolve and reveal the surprise.


  • 1 x 4lb box of ARM & HAMMER™ Baking Soda (makes 8-10 eggs)
  • Miniature dinosaur toys

  • Spray bottle for vinegar (optional)


  1. Add ARM & HAMMER™ Baking Soda to the bowl.

  5. Cover the dinosaur with more baking soda mixture and then form it into an egg shape, tightly securing the dinosaur inside.
  6. Lay your dino eggs on a baking sheet to dry overnight.
