Jumping sodium: an amazaing experiment!
Test tube has a layer of water at the bottom and a layer of petroleum above it. Sodium is denser then petroleum and thus sinks in it, however as soon as it touches the water it reacts with it (2Na + 2H2O = 2NaOH + H). The hydrogen bubbles produced push sodium up and when they detach it sinks again.
That's an amazing experiment! I wish our school would have that.
