We began with a small glass vase. Actually,that's not true. We began with an empty 20 oz. bottle but after watching Café Ole wrestle with that for about 2 minutes, I got out a short glass vase. It was far too difficult to get the play-dough to stick to the tall, plastic 20 oz. After we figured that out, we used play-dough to shape a mountain around the glass vase.
Tip: If you do the same, say good-bye to your little glass vase. Ours had such a small opening, I could not get the compacted baking soda out to save my life. Before I trashed it, I let it soak for about a week. For real.
Tip #2: You aren't going to want to re-use this play-dough again either. In case you didn't know.
Then Café Ole added some dinosaurs to the area. A few of the little trouble makers wouldn't stand up straight, so Café Ole devised a genius remedy and jammed their little tails into the play-dough. Serves 'em right. Dang out of proportion dinosaurs.
So, after we got the scene like we like it, we just added baking soda to the vase. It had a small opening so we used the little funnel that came with my iron. Then we added red food coloring to vinegar and poured it right in. Over and over and over again.
It worked great.
Sorry these are only "after" shots. If I had shot photos while the hot lava was oozing I would have missed all the fun!

What a great little science project.
ReplyDeleteSo Cool!! with Hot Lava!!
ReplyDeleteso cute.
ReplyDeleteVery cool. I think next we should figure out how to make a pyroclastic flow and bury a city with hot ash for 2000 years. Fun!
ReplyDeleteCharley still talks about pyroclastic flow. Seems to have made an impression on both of you.
