(CBS NEWS) — A six-year-old, determined to raise money to help his father pay for his cancer treatments, has raised $10,000 in one day. He did it the old fashioned way — making lemonade out of lemons.

Although he may be young, Drew Cox of Gladwater, Texas understood that his father, Randy Cox, was sick and money was necessary to help make him better. Randy had been diagnosed with with seminoma, which is usually a type of testicular cancer but appeared as tumors in his chest and other locations, MSNBC reported.

So, the little entrepreneur started his own lemonade stand to help out with the payments. “I just made this because I wanted to help him pay his bills,” Drew told CBS affiliate KYTX in Tyler, Texas.
