Tickets on sale for October's Chicago Ideas Week

CHICAGO (WLS) -- Tickets went on sale Tuesday for October's Chicago Ideas Week festival.

Some people in the Loop got a preview and a ticket to the festival. An event in Daley Plaza let people throw yellow paint-filled balloons at a message wall. If they hit the target, the paint caused a positive message to appear.

There were some celebrity balloon throwers as well, like former Bear Israel Idonije.

Chicago Ideas Week runs Oct. 16 to 22. For more information and to purchase tickets, click here.
