A little bit of everyday magic from Botanopia. Stick this Greenhouse Glow rainbow maker on a sunny window, and when the light hits it, the special diffraction foil scatters rainbows across your walls and floor. They move with the sun through the day and change with the seasons.

It works on the same idea as the prisms we all loved as children, but it is flat, neat and far easier to live with. It comes in shiny, rigid gift packaging with instructions, and it peels off cleanly with no residue if you want to move it. A cheerful stocking filler, and a lovely reminder of whoever gave it every time a rainbow appears.
