Potassium Permanganate - "A curious reaction is observed when one adds concentrated sulfuric acid to potassium permanganate. Although no reaction may be apparent, the vapor over the mixture will ignite paper impregnated with alcohol. Potassium permanganate and sulfuric acid react to produce some ozone, which has a high oxidising power and rapidly oxidises the alcohol, causing it to combust. As the reaction also produces explosive Mn2O7, this should only be attempted with great care."
There's that "chemistry" again, starting fires and causing explosions!
People often misinterpret what I say about chemistry. I love chemistry, in theory. In practice, though, it's so difficult to engage in it without someone getting burned.
It should only be attempted with great care.
For my students choice assignment I decided to do another flower, but added an extra visitor. Watercolor pencils.
Cameron Currie Lab -- MSB -- CALS -- UW-Madison -- This picture is of an Acromyrmex volcanus colony maintained in the lab. These ants are located on a spongey fungus garden which they grow themselves. This colony of a leaf cutter ant species cuts leaves, and then incorporates the fresh leaf material into the tops of their gardens. Leaf pieces are cut to a small size ( * notice green leaf fragments in the fungus near the ants ) and then tufts of fungus are "planted" on the leaves. The fungus then uses the leaves as a substrate on which to grow. Notice the fuzzy white material covering the ants. This substance is actually a bacteria that produces antibiotics which protect the the ant's cultivar ( farmed fungus ) from harmful pathogens. In fact, the ants have specialized gardening and weeding behaviors where the ants will rub the white bacteria onto parts of the garden that are infected so that the actibiotics produced by the bacteria may come into contact with the infection.

Great glass lab beakers and jars from a Missouri estate. The tallest is 4.5 inches tall and the smallest 2.5 inches tall. Left the residue in for the photos so there would be glare, but it's all cleaned out now. Eight pieces in the group.
Recent find from a Salvagenation road trip. It's always fun to bring home a truck full of really unique items and this time was not a disappointment.

Whenever I can, I like to get down low when I'm taking photos of the dogs, as you get a whole new perspective from their level. This backfired on me a little.... Abby saw me sitting down on the beach when she came barrelling out of the lake at top speed and decided I must be waiting for her to come play. So, just in case anyone is wondering what it looks like just milliseconds before getting body-slammed by the world's happiest yellow lab, with wet fur, sand and doggy drool flying everywhere, this is it. No cameras were harmed in the making of this photograph....but it was close!
