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

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 were feeling down, depressed and isolated.

Golubic said it was her carefree seven-year-old self that inspired her.

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 some serious history of humor from ancient to modern times.

The museum also explains humour styles, from word play, slapstick, toilet and dark humour to satire.
