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.

Not surprisingly, Haas' gesture was followed by dozens of Facebook comments thanking him.

"You're one amazing young man," Ann Marie Smith Braga wrote on the "Soldier for a Soldier" wall. "Our family lives on Hanscom AFB in Bedford, Mass. We are an active duty Army family. I want to thank you from all the Army families here at Hanscom."

"What you have done is unheard of in this day and age," April Johnson wrote. "I am so grateful for you and others like you! I am featuring your story in my newsletter. You are a very wonderful boy!"

"If everyone was like Brendan there would be no wars," Bob Wade wrote. "Brendan, being 9 years old you may not fully realize how incredibly thoughtful your gift is but someday you will. I hope you continue to do great things in your life. The world needs people like you."
