I think gallium is petty cool because it has a melting point of about 30 degrees, so it will melt if you hold it in your hand! It’s also used to make blue LEDs.
Yes that’s right. My mum once told me that when she was at school she used to play with mercury! A good few years later though they discovered it was harmful, which is why they stopped making thermometers with it!

Have you ever held mercury before, because I heard it was poisonous if it sinks into your skin.
