Erupting Dinosaur Extinction Slime

Erupting Dinosaur Extinction Slime, the name alone tells you how much fun this experiment is!  I let my son name this post for me. Isn’t it perfect? This is a fizzing and foaming reaction that ends in a slime you can play with!

I wanted to try making something fun and erupting for our dinosaurs this week. I have seen lots of variations of erupting dinosaur eggs that are so much fun. But this erupting dinosaur extinction slime is even cooler!  My kids went nuts over this.

If you want a regular volcano activity instead of this slime version, check out my post on how to make a volcano.

How to Make the Erupting Dinosaur Extinction Slime

This is a simple slime to put together and will create an amazing reaction that kids will love!

Supplies:

1/2 c. White School Glue

2 Tbsp Baking Soda

1 Tbsp Contact Solution (with Boric Acid included- if you do not have it, a tsp of borax will work)

1/4 C. White Vinegar

Red and Yellow Food Coloring

Jar

This erupting slime is a very messy project, so do this on a tray to collect all that overflows when the eruption happens.

Start by mixing the glue and baking soda in the jar.  Add a few drops of yellow food coloring and stir it in.  Drop a few drops of red coloring on top after, but do not stir it.  This will create a color changing reaction as it erupts, too, making it look like hot lava.

In another cup or small bowl, mix together the vinegar and contact solution.

Pour the vinegar solution into the jar while stirring.

This will cause an amazing foaming color changing reaction that overflows all over your dinosaurs burying them in boiling hot lava!

When you take what’s left in the jar and what over flowed and play with it, it turns into an awesome slime that you can continue playing with.

It will start a lot stickier, but will form into more of a slime as it is continuously mixed and kneaded. Don’t worry, your kids will do that just fine on their own as they play with the erupting lava goo.

See!  Now it’s slime!

The Science Behind This Erupting Slime:

There are a few different chemical reactions happening in this slime.  We have the baking soda and vinegar reaction. The reaction between the baking soda and vinegar is an acid-base reaction. When the two combine, a gas is released.

The slime reaction is a chemical reaction between the glue and the boric acid.  The glue has polymers (long flexible molecules). When the boric acid is added the glue it links the polymers into a longer chain making them less flexible and rubbery.

Dinosaur Extinction

While we don’t really know how the dinosaur extinction happened, there are certainly a few different theories out there. A volcano eruption is a possibility, right?

Other theories include: climate change, meteorites, diseases, food chain imbalance, and the great flood.
