The boy raised $5,000 at his Kool-Aid stand, according to newsnet5.com. That money will help pay for his grandmother's funeral.
Bobbie, 52, and her grandson Michael were "extremely close," according to the report, and the Kool-Aid stand was his idea.
Thousands of people heard about Michael's Kool-Aid stand and went out of their way to help buy a cup or two from the third-grader on Rockwood Road in Garfield Heights, Ohio.
Bobbie's funeral will be held on Tuesday in Cleveland.
