WBRZ - Baton Rouge

The green revolution took over downtown Baton Rouge today.

People at the Louisiana Earth Day Festival tested out environmentally friendly gadgets like a solar powered backpack that charges electronic devices.

A group of students from Baton Rouge High School showed off their homemade solar powered car.

There were also plenty of hands-on activities, from making mud houses to mixing bird seed.

The environmental festival ends at 8:30 tonight. It's free and open to the public.
