I was at the Cincinnati Children’s Museum in the L.I.T.E. lab and I saw a man pour liquid nitrogen in some tin foil to look like a volcano and it formed a reaction making a lava tube. When it formed the tube he taught us about earthquakes and where earthquakes spread around the globe. A lot of vocanoes happen in Yellowstone and Hawaii. He said the earthquakes are caused by techtonic plates rubbing together. Then the teacher got out his seismograph app and I pounded the table and made vibrations and the seismograph tracked the vibrations. And then after the experiment was done he showed me the nitrogen. You should go visit the L.I.T.E. Lab in Cincinnati!
