Did that just mess your head up? Nope, you're not seeing an illusion. The upside down house is not caused by some freak of nature but a deliberate action by some really rich guy in Poland. This polish philanthropist wants to remind people of wrongdoings (note the typo by Reuters in the link below) against humanity through this house.
And apparently it works really well. Workers that built this upside down house needed to rest every few hours while visitors get sick after just a few minutes in it. Just looking at the video may make you puke! Ok, I'm exaggerating.
But seriously, now you know the secret of getting people to listen to you.
Step 1: Get an upside down house.
Step 2: Lock people in it and throw away the key.
Step 3: Loop your desired message until they puke.
Step 4: Profit!
