- •GalliumOf course Gallium has to win - it frickin' dissolves other metals. They don't have a chance against it. Oh and it literally melts in your hand - but hopefully not in your mouth.
- •BismuthOoooohh the crystals, so fun to look at and more fun to make! Plus it's the most naturally diamagnetic substance around, almost to the point of levitation.
- •MagnesiumYou know that brilliant bright white light in fireworks? That's Magnesium. Not only is it bright but it burns hot and slow - that glowing exploding dandelion shaped firework, after the initial burst, is basically a sphere made of burning magnesium, so bright you can see it as glowing white all the way from the ground. I hear it's good to eat some too - but probably only in very small pieces.
