A 9-year-old Massachusetts boy who earned an all-expenses-paid Disney World vacation through an innovative Facebook experiment gave the trip away to the family of a soldier killed in Afghanistan.

Brendan Haas created the "Soldier for a Soldier" Facebook page in February. Inspired by the story of the guy who, through a series of trades, turned a paper clip into a house, Haas started with a toy soldier and eventually traded up to $900 worth of Disney gift certificates, airfare and hotel credits.

On Memorial Day, Haas gave the trip to the family of U.S. Army Lt. Timothy Steele, a 25-year-old soldier killed in Afghanistan last year. According to NBC's WHDH-TV affiliate, Haas pulled the name of Liberty Hope Steele, the fallen soldier's now 2-year-old daughter, out of a hat, and surprised the Steele family at their Duxbury, Mass., home
