There are 25 six-foot-tall milkshakes and people are encouraged to take creative pictures and submit them on Facebook or Instagram using #ShakeItUpHBG. If your picture is chosen, you will win $500.

The effort began Monday, and so far, there have been more than 1,000 submissions and two winners.

“I thought it was a great idea to help bring foot traffic to downtown Harrisburg and keep people interested and keep it top of mind and a good way for people to get some free cash,” Ron Kamionka, of Shake It Up Harrisburg, said.

Shake It Up Harrisburg runs through August 28.
