Glow In The Dark Stones in Small Canvas Gift Bag (Pair of 2)
Strike these stones together and watch them glow in the dark.
Striking these stones together separates the negative and positive charges within the quartz.
Enough voltage is obtained in order to cause an electric arc when the two charges rejoin to neutralise each other.
This natural phenomenon is known as piezoelectricity.
Strike the stones together briskly in a darkened room and watch them glow.
Instructions included.
Each pair of stones comes in a drawstring pouch for safekeeping.
CONTAINS 2 GLOW STONES
Suitable for children aged 11 and up. Adult supervision required.
Caution: Use hand and eye protection (Gloves & Goggles) when performing this experiment.
