Are you hot? Are you cool? Settle down, I'm talking about your temperature
Did you own a mood ring? Were you ever confused as to why it would turn blue, even when you didn't feel the slightest bit sad? Or why it would turn blue-green, even though you had mountains of homework to complete?
SPOILER ALERT: This is because the material found in your mood ring does not actually read your mood - it's actually made from a thermochromic material that changes colour based on your temperature.
Explore and experiment with these colour changing materials in this interesting chemistry kit. Also investigate exothermic and endothermic reactions using everyday materials. A fun little kit!
9+ with adult supervision.
