    perfect

  • I bury a few broken matches, light one, and the volcano like reaction becomes self-sustaining. I have the students calculate the change in enthalpy, entropy, and Gibbs. They can draw a rough energy diagram. It is a flash experiment to motivate them through some tedious math.
    Good amount and very fine

  • I don't know of any reason for having a bigger jar of this stuff. It is a nice amount. This is very fine powder, or maybe just really small crystals, so use less than you would think.
    High quality
