Fizzy Dinosaur Eggs

  • 2 Tbsp. of  water
  • Gel food coloring
  • Small plastic dinosaurs

Directions:

  1. Mix baking soda, water, and gel food coloring in a glass bowl until you're able to press the mix together without it falling apart. Note: If it's too wet, add more baking soda - If it's too dry, add more water.
  2. Mold the mixture into egg shapes around a small plastic dinosaur.
  3. Lay them out to dry on a piece of cardboard, a paper plate, or even in an egg carton.

Release the dinos!

Once they're dry, your kids can find creative ways to get the dinosaur eggs open to reveal the dino surprise inside! Here are four ideas on how to release the dinosaurs:

  • Chisel them open. Use tools safe for your kids to use, of course!
  • Spray them with vinegar and watch the eggs fizz.
  • Drop them in water - like a warm bath - and watch them disintegrate.
  • Fill small squirt guns with vinegar and shoot at the eggs - this is best done outside. Remember to rinse the squirt guns after use.

No matter what you do with them, your kids are guaranteed to have a dino-mite time with this STEM activity!
