Welcome to CoreFacts, where we're always short on time and big on science. I'm Steve Sobieszczyk. Let's get right to it, today's question is:

Doesn't glacier ice last longer in drinks?

Surprisingly yes, but only because the ice crystals are larger. Crystals melt from the outside and large crystals expose less surface area per unit volume of ice; therefore, ice with larger crystals melts more slowly.

And now you know. Join us again every weekday for a new CoreFact. For other CoreFacts, or for CoreCast, our in-depth science podcast, go to usgs.gov/podcasts. We are still happily accepting your science questions, so if you're curious about something that we can answer, send us an email at corefacts@usgs.gov or leave a voicemail at 703-648-5600, long distance fees apply.
