Three Long Island siblings are heading into the Shark Tank tonight to try and make their late father's dream come true.

As News 12 has reported, FDNY firefighter Keith Young, of Wantagh, worked at Ground Zero and died after losing his battle with brain cancer earlier this year.

His wife died of breast cancer back in 2012.

Before he passed away, Young invented a cutting board called the Cup Board Pro.

His three children will be on tonight's episode of Shark Tank to pitch the idea.

There's a viewing party planned at Wantagh High School.
