Using nickel wire normally sold for e-cigarettes and a *GlowStick* inspired construction - this fast reactor build used LiAlH4 as the Hydrogen source. Of course, a real, or home made (more later on that) Celani wire could be used.

Calibration data here:
Alan Goldwater has kindly produced a best guesstimate of an extended calibration curve.
"Reactor was taken for the measurement (still under the pressure of hydrogen) and resistance is just perfectly same as it was during the calibration.
Measurement was performed at the same ambient temperature."
