"Fighting Gravity" helps fight cancer.
The group that makes you wonder "how'd they do that" returned to its roots at Virginia Tech.
These Hokie fraternity members definitely wowed the audience.
They became famous on the show "America's Got Talent."
Friday night Fighting Gravity showed off their talents.
It was a sold out crowd in Blacksburg, about 3-thousand people were inside Burris Hall.
Fighting Gravity headlined a Relay For Life event, the performance art group uses black lights to create illusions onstage.
Many people brought their families along to watch.
"My grandson really likes defying gravity, fighting gravity and it's his birthday present so that's why we're here. We're also here to support the cancer association," said Pam Burnette.
"I think this is a great thing. It's the best thing to happen to this area for quite some time," said Charles Burnette.
Before the main event there was a dance competition which included the university's High Techs, salsa dancers, and the Low Techs.
The Low Techs are a group of guys whose less than perfect dance moves got a big laugh from the crowd.
One organizer says the event brought in 20-thousand dollars for cancer research.
