DES MOINES, Iowa -- A central Iowa man is collecting something small and it's making a big difference for a local organization.
"I've been saving all the tops for the past five years. Kim and Christy are surprised how many I've saved from the last time," Dan Williams of Humboldt said.
Williams donated more than 186,000 soda can tabs to the Ronald McDonald House in Des Moines on Sunday.
The pop tab donation is a long-standing tradition of the organization to help pay for rooms of guests with sick children.
With Williams' donations, 12 guests will be able to stay in the house for a week -- free of charge.
The only person to ever beat Williams' tab donations, was Williams himself.
Five years ago, he donated 200,000.
It's the largest donation in the Ronald McDonald house history.
