With just a few household items like vinegar and baking soda, create a working volcano model that spews bubbling “lava.” You can even use the plastic volcano form as a mold to create an ice volcano with LED lights. Known as cryovolcanoes, ice volcanoes were first seen by the Voyager 2 space probe on Triton, Neptune’s largest moon.
