A new museum of laughter is offering to put people through the spinner to wash away the negativity of modern life.

Visitors to the HaHaHouse in the Croatian capital, Zagreb, are blasted with a puff of white smoke once they step inside to blow away their worries before climbing into a "giant washing machine."

The "centrifuge of life" then whips them away Willy Wonka-style down a twisting slide into a pool filled with little white balls, where their journey to a happier place starts.

Its creator, Andrea Golubic, said she had the idea for the museum during the pandemic when many people felt down, depressed, and isolated.

"I realized that I had a mission – to heal people with laughter," added the upbeat 43-year-old.

The idea "came straight from the heart," Golubic told Agence France-Presse (AFP), and on that very day, I listed 78 exhibits; that's how the HaHaHouse began."

Golubic said it was her carefree 7-year-old self that inspired her – "a picture of me as a first-grader, with wide teeth and dying of laughter. I was constantly joking as a kid," she said.

Visitors press a button to be "disinfected from negativity" as soon as they step inside the museum, which has eight interactive zones.

One has a rubber chicken choir cheerfully cackling out hits like ABBA's "Dancing Queen," there is a karaoke room with distorted voices and a "Sumo Arena" for wrestling in puffed-up costumes.

There is also a serious history of humor from ancient to modern times told through theatre, film, or the net.

The museum also explains humor styles, from wordplay, slapstick, toilet and dark humor to satire, with the help of some choice one-liners.

"I've had so much plastic surgery when I die, they will donate my body to Tupperware," is one of the featured singers from U.S. comedian Joan Rivers.

Inner child

Golubic said the HaHaHouse is drawing everyone from small children to the elderly, with grown-ups seeing it as a good excuse to play at being kids again themselves.

"All those who still feel a bit of childish joy and embrace their inner child will recharge themselves," she insisted.

Pensioner Bruno Dadic told AFP he was "delighted" by his visit "as there is never enough humor in life.

"Laughter is a medicine for the soul," he said.

Zagreb's psychiatric hospital has expressed interest in organized visits; schools and retirement homes are also linked.

"The museum is great," said Aleksandar Suka, who celebrated his fifth birthday with a visit.

Accompanied by his mother, the little boy said he loved lying on the "Bed of Nails" since they tickled him.

Singer Zorica Bucic, from the coastal town of Split, said the museum was perfect for our times "when we are bombarded with so much bad news.

"Entering here is like entering childhood, being relieved of all problems. If you could come here more, there would be no need to pay a psychologist," she said.

Indeed, laughter is a defense mechanism that gives people the strength to face their problems, psychologist Petar Kraljevic told AFP, saying he loved the idea too.

"If a prescription for three hours of laughter per 24 hours could be written and followed, that would certainly give positive results."
