Next Week in The Negev

Not much to talk about this week--we've been doing the usual morning Belmonte and afternoon mentoring labs. Except Monday, because we had no good lab access and we couldn't use the TEM. So we just played around with dry ice and liquid nitrogen and eggs in HCl. Water: denser than oil; ethanol: less dense. But miscible in all ratios, which means that there is some ratio of water-to-ethanol that allows non-polar oil bubbles to simply hover in the middle. Then when some transition metal ions are injected into the bubbles (i.e.: injecting water into oil), the now-green bubbles sink to the bottom of the beaker. Finally, though, they pop and the green diffuses and the oil rises to the middle again.

And next year in Jerusalem.
