The rainbow would be made by very powerful lights. No real sun, rain, or mist required. |

It would be like the aurora borealis but in your back garden!.. not seeing a large point to it, but it would certainly be novel..! |

It's a group of floodlights? |

I haven't determined the exact technology that would be used. Possibly floodlights, but I think laser lights might do the job better. |

I find a few puffs of smoke and a mirror in

It would take a lot of power to make a bright rainbow outdoors, but there are several makers of "rainbow lamps" which use a halogen lamp and a prism. [link] These work quite well indoors, and could brighten up an awning outdoors. |

Lasers are unsuitable, as they create a very narrow color spectrum, and a rainbow requires broadband white light. |
