You could call it thrilling, or scary, but either way it's for a good cause.

Hundreds are going "Over The Edge" this weekend, rappelling down the side of the W Hotel in downtown Austin.

It's all to benefit the Make a Wish Foundation.

KVUE's Jason Pucket and Stacy Slayden even grabbed a harness and buckled up.

Each person went down the 38 stories, symbolic since nationally the foundation grants a wish every 38 minutes.

"We're actually mirroring what our kids do, we're facing our fears rappelling down the W while they face their fears through the medical process," said Katherine Brewer, president and CEO of Make A Wish.

Brewer said there are usually about 500 kids each year in Central and South Texas who need a wish.

"This wish is actually part of the medical journey, this is actually good medicine to help them get through the medical process," said Brewer.

Each wish costs on average about $5,000.

The foundation said the most requested wish is a trip to Disney World.

If the organization reaches this year's fundraising goal of $650,000, the Texas branch can grant the wish of every child currently on their waiting list.

"From our perspective, we can't think of a finer organization with a greater mission statement than Make A Wish," said Bob Barnes, president of event sponsor IBC Austin.

Michelle Barry is a longtime supporter of Make a Wish.

"I just decided to take the next step for the second year in a row," said Barry.

She said her son is already wanting to help.

"He talked about this even for months after I did it last year, and said when he grows up he wants to climb down a building too," said Barry.

And with each person rapelling down, they're hoping the fundraising total only continues to go up.
