Italian Man Hospitalised After Falling Into 'Black Hole' Museum Exhibit
So it came as a shock when a man in his 60s was left hospitalised after he fell in to a 2.5m (8.2ft) deep 'black hole' in an art museum, at the Fundação de Serralves, Museum of Contemporary Art in Porto, Portugal.
The installation, made by the British sculptor Sir Anish Kapoor, has left an Italian man injured after he fell through the exhibit - despite warning signs and security, reports 9GAG.
Though it may look like something from a Looney Tunes sketch, upon first sight the exhibit - called Descent into Limbo (1992) - appears to be a dark hole, meant to look like an abyss, fixed in the centre of the floor inside a large concrete cube room, with a single door to enter and exit.
In order to give the illusion of a bottomless void the sides of the hole are coated in black pigment, which gives the hole a much more menacing and infinite feel to it - luckily for the man that fell, it wasn't infinite, but a not-too-nice 2.5m (8.2ft) fall.
Visitors enter the installation through a small doorway leading into a freestanding concrete and stucco room, measuring approximately 20 square feet. This is all designed to give the appearance of an endless chasm in space - looking down into it is said to be a dizzying experience.
It's been reported that the museum said all security and safety measures had been followed correctly - this all included warning signs and a member of gallery staff positioned inside the installation.
It has been temporarily closed while the museum looks into exactly what happened - but they do hope for it to reopen it in a few days.
The man behind the exhibit, prize-winning artist Kapoor, is well-known for playing with optical illusions that create the impression of infinite depths with his work.
Back in 2016 he even secured the exclusive rights for the pigment Vantablack - it was developed by British company, called NanoSystems, and the pigment absorbs 99.96 percent of light.
However, Descent into Limbo was created 24 years before Vantablack was even announced to the public, instead he made the installation using a dark paint that produces the same black hole effect - so equally making the black hole that bit more daunting to look (or fall) into.
The Italian man who had his own Road Runner moment is reported to have left hospital and gone home to recover.
