You know what's fun? Watching K-Pop idols freakout on roller coasters.

See Exhibit A: Jonghyun and Key screaming bloody murder:

And then there's 'D-Lite' Daesung not looking so delighted.

You know what else is fun? Riding these for your self! Seriously, what's a summer vacation without a great adventure? For those in the tri-state area, make sure to check out the Six Flags Great Adventure Jackson, New Jersey location when it opens with its new ride--the Zumanjaro: Drop of Doom.

As Six Flags fans already know, the amusement park is already home to the tallest and fastest roller coaster in the world, the Kingda Ka. Well, the Zumanjaro is built on the face of the Kingda Ka, making it the world's tallest drop ride, 41 stories tall and a 415 feet drop! Can you handle a 41-story plummet that speeds up to 90 m.p.h? If you are, the ride is scheduled to open on July 4.

Make sure to check out the sick new ride this summer--and who knows? Maybe you'll bump into some familiar faces....

SHINee off to the Six Flags in Los Angeles, California location earlier this year. They know what's up.
