one myth from the movie: not quite a spoiler, as it is seen in the trailers: they have a ride vehicle which consists of a glass ball with a self propelled carriage inside it. access is through a round opening in the ball which is closed with a glass dome to complete the sphere. is it possible to make a sphere and closure so it secures with only a minimal visible seam, out of glass, OR out of a material which might be referred to as glass?

Including "transparent aluminum"?

Including "transparent aluminum"? well, that could be in a replicate the results category. here is a picture showing the closure.

there are a couple if incidents where a barely licensed helicopter pilot removes a hand from the controls to gesture or to adjust his sunglasses.
some people have said this can't be done. does anyone have any inside knowledge?

I'm wondering if we should be looking at a type of Plexiglass instead of actual glass.

1. Traction issues? 2. Ultimately it has scratches that make it hard to see outside?

1. Traction issues? 2. Ultimately it has scratches that make it hard to see outside? the size of the ball would help a bit with the traction. bigger rolling radius makes it easier to roll over obstacles. however, it also seemed to be stainproof - which would imply a hydrophobic outer coating, which is kind of the opposite of traction. the potential for scratches would be material dependent. other than an unfortunate drop on a rock, my gorilla glass phone screen looks brand new.

Next problem is ventilation. You are inside several large sheets of solid materiel. You have to have some way to cycle the air or you will suffocate the occupants fairly quickly.

Could that small metal plate at the front have a vent system?

Looks like the metal plate in the front is internal, it has a roller ball being in the center.
Next issue is how you built it. It looks like the shell is a sold piece, with just the door being the only seam. That means that everything inside that has to be built inside the sphere shell though that hole. Doable, but it makes it all the more involved. More joints means more fasteners, metal structure, and more weight.

"Traction".
Good question, as this involves weight transference inside the vehicle.
The movement is rather like one BIG hamster ball, the hamster runs up one side of the ball, and it "falls" forward.
Therefore, as long as the ball can throw its weight forward of the centre of balance, it will just "fall forward"...?... Therefore, it will need some grip on the ground in order to climb up the inside.... or otherwise, it just spins where it is?.. If the outside is "shiny", how does it get grip. If it does get grip, how the hell does it NOT end up as one big "Skid mark" all over the ball as the "mud" coated the sphere as it spins?... Hydrophobic?.. sure, how does that grip anything?... I presume rubber wheels inside the sphere, how come they dont leave skid-marks as well.

I presume rubber wheels inside the sphere, how come they dont leave skid-marks as well. my goodness, we've really pulled this one apart, haven't we. here's one that involves spoilers. the carriage inside is said to be gyro balanced to keep it right side up. during the movie, an incident happens which puts the carriage upside down in the ball. - now the structure of the carriage keeps it secure in the ball - but if it is balanced enough that the carriage can be upside down, how does it gain the leverage to drive the ball?

Same way it did when it was right way up?.. its not as if a plane falls out of the sky when its upside down is it?.. I hope not, otherwise, I just blew the laws of physics in my past.....
I expect there must be a balance point that will allow an "upside down" attitude somewhere, the how its done is buried in the Hollywood Laws of physics?...

How would you "stomp the brakes" in one of those things?... could that be how the carriage inside flipped over?... that would definitely fall under the category of spoilers. - but the key element is that the ball came to rest on level ground with the seat section upside down, like a hamster ball coming to a stop with the hamster at the top. mechanically, the machine wasn't shown having the acceleration to make stomping the brakes an issue. - which may also address the traction issues. less acceleration means less need for traction.

It's Jurrasic World, I'll bet what causes the flip has too many really big teeth and very small arms........
