KUSA - Kids at Holyoke Elementary School realized how kids in Moore, Okla. are suffering following this week's tornado, so, they got out the mason jars and went through their piggy banks.

Each class in the kindergarten through 6th-grade school has their own donation jar.

Friday was the last day of school, so Friday afternoon, all the money was counted up and handed over the American Red Cross' relief fund.

In April, Holyoke was rattled badly from a strong storm. These kids know how strong those winds can be.. and damage they can cause.
