Re-usablity

I picked these Diyas from Walmart and they are indeed re-usable. These actually are candles in a small plastic bowl! The candle burns but the melted wax does not go anywhere. It remains in the bowl only.

I light the Diyas in the evening and keep it outside and then buzaofy them after some time. The melted wax solidifies as the temperature outside goes below zero in the night.

In the morning you have the diyas ready for re-use :-)
