Here’s how PinkGirl’s volcano science project turned out yesterday:

If you’ve been around for a while, you might remember FavoriteSon’s volcano project. Here’s an excerpt from that blog post:

We end up at Michael’s craft store with four packages of quick drying clay, a terra cotta pot and . . . a rocket engine. Yes. Michael’s sells rocket engines. FirstHusband is smiling and FavoriteSon is explaining how there really IS a type of volcano that explodes like that . . . The boys spend all morning Saturday wiring and soldering. Then they go into the backyard to test it before they make a terra cotta pot LOOK like a volcano. It works. It explodes. I look at FavoriteSon and say, “When you get sent to the office on Monday, give them your dad’s work number so he can explain how that’s perfectly safe.” . . . Then it’s tested again, this time adding sand to the top of the volcano so it shoots dirt up into the air and looks even more realistic . . . either FavoriteSon will be suspended or he will get an “A” on this project. (postscript: he got an “A”)

So. This time, explosives are NOT an option. PinkGirl has the same science teacher FavoriteSon did. No playing the “I had no idea” card. But PinkGirl wanted “a BIG explosion.” How to do that without ignition? FirstHusband wanted to buy a portable compressor, but his attempt to justify the expense by coming up with other things to do with it after making a volcano explode?

FAIL.

So my father (SuperPappy) suggested the shop vac reversed. The lampshade idea came to me during a severe allergic reaction to crafting after my husband said the words “paper mache” to me. We picked out a dirty, torn lampshade and got a 25% discount. Final Sale. No returns.

No problem. Crafting avoided.

As you can see, the explosion was a HIT. The ash went higher than the fence.

Here’s the written report PinkGirl wrote to accompany the volcano shown in the video:

“Volcanoes are amazing things of nature and only God can create them. Still for my project I tried my best and I also had fun while doing it. From deciding what type of volcano mine is or what type of eruption it will have it was a fun learning experience that I would love to tell you about.

The First thing I did was paint the lampshade (which is my volcano). It was actually a lot harder than I thought it was going to be because I had to mix paint to find the right color. The second thing I did was cut a hole in the box big enough for the pipe. Then I cut the top of the lampshade out with bolt cutter. (It was awesome!) After that I measured and cut the pipe to the right size with a hack saw. (My dad helped a little for this part but I did cut with a hack saw.) Next I glued the pipe to the adapter and cut the small pipe to the right size and glued it to the adapter and the elbow of the other pipe. Then I put another hole in the side of the box and put the side pipe in it. Next is my favorite part. I put coal in a bag and crushed it with a hammer. After that I poured the ash and coal in and covered it with saran wrap. Then I painted the box green and put the “Snow” on the volcano. The last step was decorating it with little touches to make it look better.

During the process of building my volcano I learned all about Composite volcanoes and plinian eruptions. Composite volcanoes are made out of ash, tephra, and lava. Plinian eruptions are violent and have lots of ash and poisonous gasses. Mt. Saint Helens was a composite volcano and had a plinian eruption.

I always thought a volcano just meant lava and smoke but I now understand that volcanoes are much more complicated than that. God must have had fun designing and creating volcanoes. He is a very creative God who has an amazing imagination. Volcanoes are dangerous magnificent things that create new land, give us dazzling treasures, and really open our eyes to show us how marvelous our world really is. I can only imagine what other planets are like.
