``People don't talk about burps and farts and go into detail of how they work,'' said 18-year-old student Pamela Yap as she made a beeline for the interactive<sup>1</sup> displays. ``They don't teach us this at school.''

The squeaky-clean city state, which has long barred spitting and enforced fines for not flushing toilets, is the first foreign country to put on the show apart from Canada, where it was created five years ago.

The show was brought in to help people understand and perhaps better manage their bodily functions, said Chew Tuan Tiong, chief executive of the Singapore Science Centre, which is hosting it.

"Visitors will go away with this idea that all of these gross functions are actually very important and have a purpose in their bodies," Chew said.

Children can climb up a rubbery wall of simulated skin to explore warts² and pimples³. A cave-like walk-through nose sniffs⁴ and sneezes on the unfortunate passerby⁵.

Visitors can challenge their sense of smell and learn about odor-causing bacteria by sniffing⁶ unmarked bottles containing mouth, foot, anus and armpit scents⁷.

The exhibition delves⁸ deep into the physics, aromatics⁹ and even the timbre¹⁰ of flatulence. To up the grossness factor, visitors can pump on levers at the vomit¹¹ and burp machines for maximum effect.

Children squealed¹² in delight at the exhibits but adults long taught to regard the intimate workings of the body as impolite seemed to get the most out of the show.

``Grossology'' heads for Taipei, Seoul and Hong Kong after it wraps up in Singapore on March 4.
