Some people donate to charities when they have a lot of money. However, one wealthy real estate developer is donating in a much more spontaneous way.

Jason Buzzi and Yan Budman, better known by the twitter handle @HiddenCash, are backing the movement by hiding money all over major U.S. cities.

While they were in San Francisco in May, they hid envelopes containing money throughout the city. On the envelope he wrote "Twitter @HiddenCash follow us for more and tweet when you find."

The only clues are left on his Twitter account, which has 150,000 followers. When someone finds the money they tweet their find, along with a picture of themselves with their cash prize.

The men told the AP that they are inspired by the people who are participating and encourage them to share the money.

This weekend, @HiddenCash is in New York City. However, this time the cash is hidden in Pez dispensers. Three dozen dispensers were filled with $100 bills and scattered across Brooklyn's Coney Island and Brighton Beach.

The AP reported that one boy found a Superman-shaped dispenser with two airline tickets that are good for anywhere in the US.
