Hah! One of the best investments I've made. They're not even terribly
expensive from a certain seller on eBay, even shipped internationally.
I had that iodine eat through two bottles before putting it in there. The second one was a Mason Jar, and it chewed a small hole in the lid after just
a week. Unbelievable.
I was skeptical at first that the Schott-Duran bottle with the red cap and foam-backed PTFE liner would be any better, but I'm happy to say that my
suspicion was unfounded. I have little doubt that they could even hold bromine, which is far more clever as escape artists go.

Something interesting: just found a test tube what fluoresces under UV light. What could the glass contain? Any ideas?(:

EDIT: B10 double surface (davies) condenser at -5*C for preparation of ethyl bromide. 80% crude yield on 150mmol scale.

That is probably colder than -5 °C. It is likely like -20 °C.

Nope. Its -5*C thermostatted with a refrigerated coolant circulator. All that ice didn't suddenly appear, but rather over a period of about two hours.
Its unfortunate the display on the coolant circulator isn't visible in the background.

This spark is rather fast so if you blink it's easy to miss it. And getting the video to stop on the spark was tricky too. I was able to make a thin
spark 7.5 inches with just the melon resting on the dielectrics, that is the teflon and acrylic sheets without the top jar. Earlier experiments with a
grapefruit proved less spectacular. Little flecks of yellow light flash off the skin of the grapefruit when it sparks, perhaps from traces of sodium.

Pieces of white phosphorous glowing in the dark!
Actually, they seem to be more bright then they are,because I've used a long exposure time.

DL Tartaric acid diisopropyl ester what is described everywhere as a highly viscous liquid what crystallized out at me after a little purification.
