Wait another 12 hours and take it out. Continue the 12 hour cycle replenishing the solution with alum depending on how big you want the crystals to grow.

*Threading tulle with conductive yarn*
**Threading tulle with conductive yarn**
We laced the tulle with some conductive yarn to see if this makes it easier to solder the crystal/sensor to a circuit.

ELECTRIC PROPERTIES OF CRYSTALS
**Capacitive touch test**
I tested the black alum diamonds by connecting them to a Bare Conductive Touch board, a dev board with capacitive touch sensing built-in. So I could see immediately if touching these crystals could trigger a response in a circuit. The big ones were perfect! The small mesh is triggered only when you touch the ones that sit on the conductive thread. See below.
