Students from all over Harrison helped to create a display as part of International Day Of Peace on Wednesday.
They created a huge peace sign by the library that's over 100 feet wide and made of 1,000 pinwheels.
Students from K-8 at Kennedy and Lincoln Schools, Hamilton Intermediate and Washington Middle School all participated in the effort.
Pinwheels for Peace started at a school in Florida 17 years ago.
This year, millions of pinwheels were planted at thousands of locations worldwide.
