volcano

One of Juma's science books instructed us how to build a vinegar and baking soda volcano. We poured into a soda bottle some apple cider vinegar, food coloring and dish soap to make it more impressive. Then we built up newspaper and tin foil to make it look like a volcano. Finally, we took it outside and plopped some baking soda into it.





And waited.

And waited.

Huh?

I poured in some more vinegar and baking soda to boost the explosion.

And we waited.

What the?

I picked up the vinegar bottle again to pour some more in, looking at the label as I did so.

Oops--it was not apple cider vinegar like I thought. It was just apple cider.

We went back inside to find something acidic to replace the vinegar. There was some lime juice, so Juma poured that in, and I added more baking soda again.




Finally, the bubbles formed enough to come out the top of the soda bottle.





Juma then enjoyed spreading the "lava" all around the dirt and rocks, pretending to destroy buildings. Little boys and lava, I tell ya.
