General Chemistry

Unlike anything you have seen before, the ColorFlame Birthday Candles burn in COLORS... the actual flame burns in brilliant hues of red, green, blue, orange & purple! The Chemical Clock keeps accurate time using energy from a battery that you make. Place the Disk and Ring Kit in a dishpan of hot water and watch what happens. Does the hole in the center get larger or smaller? Click a metal disk and watch the Chemical Heat Pack crystallize.
