Every time I say, I’m from Kansas, some genius makes a remark about Dorothy and the Wizard of Oz.

Wamego (Kansas), about 20 miles from Manhattan (Kansas) is more than the home of the Wizard of Oz museum (visited by a couple of my daughters, right, exactly as shown), where fights among the little people on the set of the movie are depicted in all their glory. It is also apparently home to the annual Tulip Festival, which ran this weekend.

A couple of my colleagues went tuliping on Saturday, and found the fair also included a lot of food and a petting zoo: a poorly supervised petting zoo, where little kids could walk in and swap saliva with a bunch of animals like cows, and llamas and alpacas, without supervision, and then go eat food or suck their fingers or whatever.

I’m told there were signs, there were wipes available, but is that really enough, especially given all the tragic outbreaks that have been linked to petting zoos? And the handwashing facilities were about 30 yards removed from this sign (left).

Having a baby around the house has introduced me to a bunch of new life necessities like soothers, gripe water and wipes. I'm not a huge diaper-changing fan, but when it’s my turn I try to do everything in a quick, fluid-like step but it doesn't always work out. The wipes help a lot.

I have a close friend back in Guelph who also uses wipes. And he doesn't have a baby.

A couple of years ago he led a discussion at a party about the political-correctness of adults using baby wipes for the not-so-clean trips to the restroom. As the

r puts it, wipes can provide consumers a "shower-fresh" feeling for their bottoms. Since the discussion, this friend reports that he has been buying wipes, stashing them in his desk and covertly grabbing one daily as he goes to have a dump.

According to the

it turns out that flushing the wipes, even if they are the flushable ones is not a good idea for the sewer systems (at least in Raleigh).

Tissues and wipes of all stripes get balled up with hair and grease in the city's pipes, creating clogs that send sewage cascading from manholes. The problem has gotten worse in recent years with the introduction of wipes designed to disappear down toilets, Wastewater Treatment Superintendent T.J. Lynch said.

"What we see a lot of times in the collection system are overflows caused by those types of materials that don't degrade like they're supposed to or they claim to," he said.

Lynch knows this from experience and because he asked the lab at the Neuse River Wastewater Treatment Plant to test several kinds of wipes to see how quickly they break down in water.

The test, performed in March, was simple: Put a wipe or a tissue in a beaker of water with a magnet on the bottom that rotates, creating a vortex not unlike a flushing toilet. The lab put nearly a dozen products through this process, letting them spin for an hour.

Toilet paper begins to break down into a milky mush almost immediately, lab supervisor Darrell Crews said. Other items survived more or less intact. Some, such as Kleenex and other facial tissues, are well-known to people in the sewage business.

"A lot of people flush Kleenex thinking that it's just like toilet paper," Crews said. "But I can tell you, Kleenex doesn't break down. You can stir it, beat on it, it's just not going to break down."

It turns out that flushable wipes don't break down either, Crews said.

I’m not sure that public data exists around the extent of use of the wipes, but I doubt my Guelph friend is the only one sneaking around with them. Having them disposed in waste baskets beside the toilet, or elsewhere in the restroom after a clean-up probably isn’t a great public health strategy. Flushable wipes, if they breakdown and don’t lead to sewage spewing from manholes, are a good idea.
