It can't just keep on going for ever. My guess is that eventually the Mercury droplet will dissipate and no longer touch the Iron nail. What is providing the energy for this?

Until I stop being able to come up with interesting videos or an overwhelming number of readers tell me I've stopped being able to come up with interesting videos. Nothing formal. Thoughts? Dunno.

Nothing formal.

Thoughts?

This was shown on TV a couple days ago on TV here in Spain but i cant find the video on youtube you can do it with water too.

When I was a kid we used to play with mercury a lot. It was fascinating that mercury was the only liquid metal. We'd push it around with our fingers. I recall that one of my high school teachers had a small bottle of it and we played with it on our desks at school. Am I going to die? (I mean, of mercury poisoning!) I’m 56.

My only suggestion would be to pick images for the header that actually represent the video -- I clicked the crafty looking metal heart picture, expecting a contraption with mercury inside it or something. The actual video was cool, but a bit of a let-down after that. :) I agree with the other commenters — please keep the science around!

Although absorbsion through the skin is slow, it doesn't take much to have permanent effects. http://en.wikipedia.org/wiki/Mercury_poisoning#Elemental_mercury Vapors containing mercury, both elemental and in compounds, are much more dangerous. Heating elemental mercury is just asking for trouble. Probably not, but skin contact should be avoided. Although absorbsion through the skin is slow, it doesn’t take much to have permanent effects.

I love science that captures the imagination. My grade school had way too little chemistry magic. Fermo-magnetic fluids are another great area of inspiration (IMHO).

A vid of that has also been posted on here, quite stunning... http://www.boingboing.net/2009/12/05/saturday-morning-sci-8.html My humble thought is that these need to continue, i always make a point of watching them.

I was just curious because I was thinking how this could be harnessed to create energy. I can't imagine it would be a very efficient fuel source but was still wondering...
