Subject: Re: [DCHAS-L] Thirteen people hurt in chemical explosion at Nevada museum
University of Wisconsin-La CrosseBy looking at the second video and the commentary it seems clear that the mixture was not faulty, rather that since one demo was already burning when the methanol was added to the second one, the methanol vapors traveled along the bench to the ignition source and flashed back. Considering the size of the bottle of methanol it could have been much, much worse. I think this is the sort of thing that has happened in the "Rainbow Demonstration". Demonstrators have just got to be trained that having open flammables (or even worse, pouring flammables) plus ignition source is a recipe for disaster.Sandra Koster, Senior Lecturer

Thirteen people hurt in chemical explosion at Nevada museum
(Reuters) - Thirteen people were hurt, including several children, in a chemical explosion on Wednesday at a museum in Reno, Nevada, where presenters demonstrating a so-called smoke tornado caused the blast with a faulty mixture, officials said.
Seven children and two adults with non-life threatening injuries were transported to a local hospital, and another four people were treated and released at the Terry Lee Wells Nevada Discovery Museum in Reno where the explosion occurred, said Reno police spokesman Tim Broadway.
The people who were hospitalized had suffered burn injuries, said Matthew Brown, a spokesman for the city of Reno.
Presenters at the museum were trying to create a "smoke tornado" in a visual demonstration they had done before when a faulty mixture of alcohol and boric acid caused the blast, Brown said.
The museum is aimed mainly at children and offers interactive exhibits in geology, astronomy, history and other subjects.
Officials said they did not immediately have details on the ages of the children hurt in the explosion, which they said did not light anything on fire at the museum.
