Are there many 400mm electricians that need leveling?
Flat earthers from all 4 corners of the globe have tried. Have you tried seeing how straight a chemtrail is using a Illuminate approved, yeti free spirit level?
These jokes are on a whole new level
UK backboxes & patresses are a different size to EU boxes, I don't see how this is going to be any more useful than a boat level.
I need one of these to prove the Earth is flat. And that gravity is just numberplay, and what really happens is quite easily explained by pure electro magnetism. Thanks.
