ROMKids Show: The One With The Explosive Earth

Tune in every Tuesday at 2:00 pm on Instagram Live as ROM Kids Coordinator and Camp Director Kiron Mukherjee combines his passion for children’s education with storytelling to bring to life science, history and art for you and your loved ones in the comfort of your own home. Kiron will share activities, easy at-home crafts, behind the scenes anecdotes and fun facts—all connected to the ROM collections.

This time on the ROMKids Show we journey to the center of the Earth to learn just how explosive our world really is! Geologist Veronica Di Cecco joins us to talk about all the ways our planet erupts from lava, to water, to even mud. Plus we’ll also discuss a few current active eruptions. Then we’ll make a few household eruptions as well, including the elephant toothpaste experiment.


  • 2 tablespoons warm water
  • 1 teaspoon yeast
  • 1/2 cup 3% hydrogen peroxide
  • food coloring
  • dish soap
  • bottle or container to erupt from

This experiment requires the assistance of a trusted adult. Hydrogen peroxide is harmful if ingested and can irritate the skin and eyes if contacted. Wear gloves and goggles for safety. Also place your bottle on top of a tray so that the eruption does not create a mess.

1. Mix your water and yeast in a separate container.

2. In your bottle, pour your hydrogen peroxide. Then squirt in a few drops of dish soap.  Finally, drop in your food coloring. If you want to create stripes, have your food colouring drop down the side of the container.

3. Pour your water and yeast into your bottle, and watch the eruption start to build!
