Kingda Ka toy coaster?

yep.

For a science fair project when I was in 5th grade, I used some Knex Rippin' Rocket Coaster that was like that but not as much like coasters like KK and Dragster. It didn't have a twist going into the top hat.

The funny thing was sometimes it rolled back or got stuck on the top!

"Yeah, K'nex are better. /scoff"

Yes, they are. I have two K'nex and both work fine. I own one Six Flags coaster and it is SBNO. Kinda like the real thing.

^LMAO!

K'Nex coasters are near-bulletproof- as reliable as B&Ms. What bad could possibly be said of them?
