My amazing friend Tiffanie posted about this story on her blog and I must share. It's an amazing program called Tipping Bucket. It helps social entrepreneurs raise the funds the need to do great work throughout the world. I donated a few dollars to help build "greenhouse schools" in Bolivia (using the ideas of greenhouses to create warmer, brighter classrooms in the cold mountains of Bolivia). I think it's an incredible idea, both the fundraising and the projects they sponsor. So if you feel you have a spare dollar, help tip someone's bucket!
