Melissa Plaskoff helped her son Hudson and his friends set up a lemonade stand to raise money for the relief effort after the earthquake and tsunami.
Melissa says this isn't Hudson's first relief effort. He raised money after last year's disaster in Haiti. That sparked an even bigger idea.
They set up a web site and Facebook page and since then "lemonstoaid.org" has exploded.
They've created more than 140 events, all run by children throughout the U.S., Israel, England and Canada.
