(50,561 posts)I mean, come on guys, nitrate some paper towels like they did in the old days.
In the 1970s we took a science class called Introduction to Physical Science. The teacher was Mr. Shaw, who was a nice-enough guy. He was also the bishop of the local Mormon church, which is why I scoff at all the people saying Mitt Romney had a "high position" in the LDS church when he was a bishop - in that faith "bishop" is one step above "churchgoer." Anyway, we were doing an experiment with mixed nitric and sulfuric acids when someone spilled one on the table. Mr. Shaw wiped up the mess with paper towels then threw the towels in the trash. Something else got thrown in there that set off the nitrocellulose Mr. Shaw made, to predictable results.
Better: a science teacher in the 1960s had bought a quart of picric acid to make antiseptic for the sports department. In a rare display of sanity the Idaho High School Athletic Association told him homemade antiseptics couldn't be used on high school students before he got started. However, he kept the acid. After I started high school, the State Board of Education got wind that a lot of high school science teachers tried the same thing so they wanted all the schools to check their science classrooms for picric acid. Ours had crystallized, so the Air Force bomb squad from Fairchild had to come in and haul it off while we all stood outside the building. LOTS of our seniors joined the Air Force that year.
I'm sorry, but a science class isn't a science class if you don't have to call the bomb squad at least three times a year to remove someone's experiment from the building before it blows out the windows.

(50,561 posts)You mix beauticians-grade hydrogen peroxide, dish soap and, usually, food coloring and put it in a flask. Then you pour a potassium iodide solution into the flask. The potassium iodide instantly catalyzes H2O2 decomposition, and this huge stream of foam shoots out of the flask. Kindergartners love it.
