basicly you collect some water before you boil the water and use the steam from it …. LOL

okay joke aside :-)

the cheapest is to steal ….eeergh borrow moms stealkettle and leed the steam into
a steam bed made of wood and 1-1½ meter of cobbertube with holes and an endcap

there is several on L J that has made one and posted them as projects

you can use one of the modern kettles if you shortcut the thermo cuout
but then you have to be very carefull not to let it boiling dry….. you don´t want a fire
now your water is steam … lol

good luck with your steam project
