This sugar glass "candy" is actually a simulation of a planet's surface when it sustains an impact. (In this case the impact was caused by a foiled-wrapped hammer.) Those craters on the moon you see are a result of similar impacts. I attended a lecture on Impact Craters and this hands-on messy bit was included for fun AND education!
I'm a transplanted New Yorker who loves the Tucson climate. On New Year's Day I have a bit of fun calling my (snowbound) east coast friends to announce that I'm drinking coffee while sitting on my patio. (:
