A group of celebs and scientists and others are scaling Mt. Kilimanjaro this week to raise awareness about a growing global water crisis. Here’s an extremely cool website that allows you to monitor their progress. Yes, you can even monitor the heart rate of Jessica Biel. Right now, it’s 1:23am and 77 degrees, and her heart is at 99 BPM, which indicates sleep. Cool. Good luck to ‘em.
