Reducing the cost of Johnny 5 / MacGyver experiments

    At a local store I could freely purchase 100 grams of LiOH.H2O (monohydrate) for just under 8 euro (or 1 Kg for 35 euro). If really needed this could be baked above 100 °C to obtain the anhydrous form.

    If I recall correctly the main rationale for using elemental lithium was that heavy water was initially employed and LiOD is difficult to come by. Without this requirement anymore (JohnyFive reported that light water works too), standard LiOH could be used. If sodium or potassium carbonate/hydroxide also work for these titanium experiments, costs and availability could be improved substantially, as previously pointed out.
