Can a glass of water go on a coaster w/o spilling?

Wednesday, January 9, 2002 3:18 PM
I was contacted by a person who works for the BBC who is doing a program that will be broadcast next year in the UK.  (She got my e-mail from my web site.)  She had an interesting question which is below:

"we want to find the most dramatic roller coaster in the world, that we could place a glass of water onto the front of and film it throughout a ride without it emptying. Do you think this might be possible? And can you suggest where we could do it?"

Does anyone have any suggestions on if this can be done, and if so, where?

Thanks a lot.  I appreciate any help you can give.

Just kidding!! I think that you would need a coaster without any negitive G's.

Gotta make sure that there is no airtime whatsoever.

If it's a really twisted looping ride, good...if not, no good.

If they keep the midcourse brake OFF, you *might& have a shot on one of those "Mad Cobra" rides. I saw @ SFA them run a train *completely* empty and some keys remained in the ride apparently from a rider on the traim *before* they sent it empty.

Not sure water would hold up very well on the vertical curves though...

You can hold a cup of H20 on XFlight and it won't spill.  But sitting on the front of the train...I don't think so.

Well, you could find someone who has maya, and this is what you do. Put a empty cup on the front of a cart that is painted with the green color paint that they use on the green screens. And have someone who is good at Maya (3d modeler used in movies) and have them add the "water" into it.

Its cheating, but its a suggestion becuase i really dont believe it is possible to do that with a glass of water or any kind of liquid for that matter without having it spill.

Give them a taping of the Pepsi commercial aired a while ago and tell them "It's already been done."  :)

In addition to not having negative Gs, the coaster would need little or no lateral Gs and bu pretty smooth or the water will "jump" (for lack of a better definition) out of the glass.

Believe me... I've tried it on two coasters about 5 times EACH... for a total of 10 times, trying to mimic the Pepsi commercial from last year.

Let me say first the coasters... Mind Eraser at SFDL, and also Viper at SFDL (a standard 5-looping Arrow).

I had the cup half filled with water each time... it will actually hold in for the first loop, but once you get to a turn, FUGGEDABOUDDIT!! The lateral G's just whip it out... not to mention any bumps in the track will help spill it... not to mention that the corkscrew definately didn't hold it in.

If you want to keep the cup 'o' H2Woah without spilling, it's going to take a LOT of technique of the rider to anticipate how to hold the cup... tilting it in turns, adding shock absorbers on the bumps... etc etc etc.

For Mind Eraser, it barely held on past the initial loops. It was too intense to keep it going without spilling all over your face (in that case, my face, and the faces of the riders behind me... er... and the people below me).

It won't work perfectly, but you can do an entire ride with maybe a little left in the end, but definately not the whole glass... it'll wind up on you and everyone around you!

yeah, I'd say a coaster with no negative g's and as few lateral g's as possible.

as for the Pepsi commercial: the guy was twirling the cup around so all the liquid would spill out.  he was trying to keep it level to the ground, but the g's of the ride would throw the Pepsi out because of the g's.  I always hated that commercial for that reason plus Coke is the freaking bomb.

I have tried it two times, 1 time it worked (some), other time it didnt.  The first attempt that failed horribly was on loch ness.  No way it will stay at the top of the second hill where you round the corner and after the second loop.  I also tried this on Anaconda at PKD.  This worked for the most part.  Only after the brake run in the turns and also before you hit the corkscrew do you really lose some.  You do good though on that ride so I would say Anaconda would be a good choice.

What about one of those old Swarzkopff loopers?  like Scorpion or Revolution?

I hate that Pepsi commercial too.  Along with Pepsi.

i was going to say....i think an old Swartzkoph coaster would be not sure about laterals though.  sooperdooperlooper comes to far as i can recal, its about 98% positve Gs, and tons of them...someone who is more Hershey-saavy might be able to correct me.  very unfortunatly this is the only Anton masterpiece i have had the pleasure of riding....but put my vote on sooperdooperlooper :)

You can put a lid on the glass....  :)  Sorry that was my smart remark for the day.  My best guess would be a Arrow launched loop that's a lil underlaunched.  That probably wouldn't dump too much water.  But you want a dramatic coaster....  Good luck!!!

I was shooting a TV show a few years ago at SFOG and one of the PR guys said that he had done it on Mindbender.
