You can go to a camping store and buy for cheap a "solar" water heater. It’s just a plastic bag with one clear side and one black side and a hose the water comes out.

My suggestion would be a series of piping, coated in black paint, water passes through it – for a larger scale. Seems a little impractical so…
Create a convex mirror, to focus the suns rays into a pot/glass that the litre of water is contained in. Focusing the sun’s rays on the water, the water can heat up relatively quickly (on a good day) (we’re talking abotu a mirror at least 50cm in diameter)

Get a cake pan as large as possible. Paint it black. Fill it with water (one liter). Cover the cake pan with a piece of sheet glass.
