What Happens When Lava Meets Ice?
This Science Channel video looks at what happens when you pour molten lava on ice. (Hint: it's not what you'd expect.) They interview the scientists involved, describe how they create the lava, and show some other tests they are running. You can find a longer video of just the lava pour here.
Remember kids, don't try this at home!

Vinegar Plus Baking Soda Volcano Eruption in a Vacuum Chamber
Here's an interesting take on the classic classroom demonstration.
While using a full vacuum is a little overkill, using a partial vacuum can better demonstrate the pressure difference and explosivity when lava emerges from a volcano. Makes it a great classroom project for older students, allowing them to make predictions, take measurements and write up their results.
