This would have to be one of the most enjoyable science experiments you can do with your kids!
Making a mock volcano is not a difficult task, but is very messy, because this volcano will actually erupt when mixing baking soda and vinegar together. Since this is a messy project, wearing old clothes is necessary as well as working on a pile of old newspapers. Working outside would be even better!
What do you need:
vinegar
baking soda
food coloring
2 litre empty plastic drink bottle
funnel
baking pan
sand
glue
dish (Cheap throw away ones are the best)
soap
warm water
Instructions:
- To make the volcano cone: Pour glue into the tray, making sure most of it is in the center. Glue the bottle in the center of the aluminum tray.
- Using your hands, cover the entire surface of the bottle with glue.
- Pour sand into the tray so your volcano looks like it’s on a beach. Be careful not to get sand inside the bottle.
- Use food coloring to make it look like it is on an island. You might want to add some water or glue to the sand, to make it stickier.
- When finished, let it dry for about an hour.
- To create lava: Add some red and yellow food coloring to your ½ cup of vinegar.
- Using a funnel, fill the bottle halfway through with warm water.
- Add a squirt or two of soap to your bottle.
- Slowly pour the vinegar into your cone.
- To make your volcano erupt: Place 2 teaspoons of baking soda onto a tissue.
- Twist up the tissue so it looks like a little pouch.
- Strap on your goggles to protect your eyes from the eruption.
- Drop the pouches into the volcano and watch it explode!
