you said the 5 metals have the same mass, but isn't mass how much space and object takes up?

[sciencetheater]

@ajitheman5 Nope, density is mass divided by volume. Mass is how much "stuff" you have, but on an atomic scale in a sense... A pile of feathers takes up the same space as a pile of rocks, but the rocks have more mass.

Isn't lead toxic

[sciencetheater]

@Maroshirby Yes. Notice I don't lick it. :) And I washed my hands after handling it...

i meant density not volume

[sciencetheater]

Density is close (humans are mostly water). However, muscle is more dense than fat, so someone who has very little fat, (a marathon runner for instance) will be more dense. One summer I was a wilderness guide and by the end of the summer I was more dense than water (I sank even if I held my breath...)

@sciencetheater lol

Great job explaining density to my daughter... Great help for her science class!

Rocks and feathers!!! yeah gave us that demo monday! Im in your period 2.

Nice demonstration. Easy to understand.

Good call. The water in my clothes is indeed only a small error among many others. (see above)
