Hard to find lights safely packaged and performing as expected.
Bought to fuel a Mamod model/toy steam engine, in place of the original Mamod fuel tablets which are becoming hard to source.
Following a suggestion on a forum I lined the burner tray with foil before spooning in the ethanol gel. It seemed to make steam slightly better than the tablets, and left little residue. Only possible downside is that the flame is even less visible so care is needed to check whether it's lit.
