"Microwave experiments cause sponge disasters"
This is just too funny.
First story:
Microwave zaps germs on sponges, study finds
Two minutes in a microwave oven can sterilize most household sponges, U.S. researchers reported on Monday.
A team of engineering researchers at the University of Florida found that two minutes of microwaving on full power killed or inactivated more than 99 percent of bacteria, viruses or parasites, as well as spores, on a kitchen sponge.
"People often put their sponges and scrubbers in the dishwasher, but if they really want to decontaminate them and not just clean them, they should use the microwave," said Gabriel Bitton, a professor of environmental engineering who led the study.
Writing in the Journal of Environmental Health, Bitton and colleagues said they soaked sponges and scrubbing pads in raw wastewater containing fecal bacteria such as E. coli, viruses, protozoan parasites and bacterial spores.
Then they used a common household microwave oven to heat up the sponges. It took four to 10 minutes to kill all the spores but everything else was killed after two, they said.
"The microwave is a very powerful and an inexpensive tool for sterilization," Bitton said.
At least 76 million Americans get sick from food borne microbes every year, according to the U.S. Centers for Disease Control and Prevention, and 5,000 people die from them.
Kitchens are a common source of these illnesses.

Microwave experiments cause sponge disasters
Reports about a study that found microwave ovens can be used to sterilize kitchen sponges sent people hurrying to test the idea this week -- with sometimes disastrous results.
A team at the University of Florida found that two minutes in the microwave at full power could kill a range of bacteria, viruses and parasites on kitchen sponges.
They described how they soaked the sponges in wastewater and then zapped them.
But several experimenters evidently left out the crucial step of wetting the sponge.
"Just wanted you to know that your article on microwaving sponges and scrubbers aroused my interest. However, when I put my sponge/scrubber into the microwave, it caught fire, smoked up the house, ruined my microwave, and pissed me off," one correspondent wrote in an e-mail to Reuters.
"First, the sponge is worthless afterwards so you have to throw it out instead of using it. And second your entire house stinks like a burning tire for several hours, even with windows/doors open," complained another.
Aaron Hoover, a press officer at the University of Florida, said several other news organizations received similar complaints, although no one had complained directly to the university.
"We figured, 'Wow, we better let people know right away that the sponge should be wet,"' Hoover said in a telephone interview.
The university issued the following advisory: "To guard against the risk of fire, people who wish to sterilize their sponges at home must ensure the sponge is completely wet. Two minutes of microwaving is sufficient for most sterilization. Sponges should also have no metallic content. Last, people should be careful when removing the sponge from the microwave as it will be hot."
