A paint composition which is a ferrofluid, for painting ceilings.
A large electromagnet on powered rollers is positioned on the floor above. It follows the location of the brush (which has an RF transponder) by short range triangulation, so that it's always positioned precisely above the point where
the paint is being applied.
Any drips are drawn upward by the magnetic field, and stick to the ceiling, not the painter.

Also comes in handy for blocking those pesky cell-phone and Wi-Fi signals...
But I do like the 'upwards dripping'! |

Well, probably not, actually. It's a ferrofluid, not actual conductive paint. Doubtful it would form even part of a Faraday Cage. |

Oh.
I thought, since it's all iron-y, that it would get in the way of electromagnetic radiation stuff. But at this point, I'll bow to your superior collective knowledge; at least until I find the time to do some research and/or experimentation. Where do you get ferro-fluid from these days? |

Well basically, you get a chit signed by your boss, and then you take it down to Eddie in stores and he gives you the ferrofluid in a can. |

[mrm] that would be great, but if the paint remained liquid and never set, there would be great danger and/or amusement if there were a power cut during a posh dinner party. |

What do you tell the drips' parents, when they come
looking for their sons whom you've taken on as
apprentice painters? |
