You can use ANYTHING!  Marbles, sticks, rope, pulleys, tracks, anything!  just make a very large contraption that does a simple task at the end and you have it. Dominos are cool too.

You might want to go to their website and try contacting them that way. Who knows? I think that might be a cool idea for a show. Having a class of school kids come in to watch them build a bike. Maybe your class could have a contest to come up with an idea for a bike. You never know. Stranger things have happened.

Personally I would use 2 metal rods and a ball bearing or marble.  bend rods so they are spaced the same with loops first and then hills.  then find a way to project marble or ? with enough force to stay on track without falling off. try different speeds and re bending rods until satisfactory results are obtained.\n\nThat would be much easier than trying to do all the math required, then obtaining the speeds and angles required to build an actual roller coaster.\nThis should be acceptable for classroom project.

If your looking for something humorous to demonstrate the science of pulleys and stuff, perhaps u could use some of the illustrations found at this website  http://www.rube-goldberg.com/\n\nThis rube guy made the funniest cartoons and they';re scientifictly accurate or at least appear so.

Go to the local college campus and advertise your lil but off. You can have an average age group, or a centralize location, or gender vs gender. The factors are endless. For example take a basic Rubik's cube and scramble it. How long will it take the the individual to give up and hand it back?\nPeople who are more mechanically inclined will generally fight with it more than most. Hope this sparks some imagination in the right direction. Have fun and good luck.

Rube Goldberg, the guy who took a simple task and made it dificult.\n1) Turning motion, like that of a shaft\n2) Striking, like a hammer on a plate\n3) Gravity motion of an object down an incline\n4) Pouring like sand into a cup\n5) Leaverage like that of a teeter totter\n6) Cutting motion like a Knife action\n\nThe best displays have a Theme and many many trials proving out their design. You get one chance when it counts.

You can use a pyramid of cards to teach coordinate geometry (tessellations).  You can use it to teach Pascal's Triangle (permutations & combinations)

Go to a "game store" and look for a three dimensional puzzle, or some other similar puzzle.\nA company called "Binary Arts" used to make a couple of good ones.

Yes, you need a lab to do this! If that wasn't clear to you, this may not be the best project to try to copy!\n\nWhy not have an idea of you own, something you can do with what you have at hand at home? You might learn something!

build a big arc out of paper mache.\ngive the lengths of straight lines to the end of the arc. \n\nhave students gague the length by "eyeballing it"\n\nthen use a piece of rope to demonstrate the actual length..\n\n.

Get a large toy clock and teach the o'clocks and thirtys first.  Then get to the fifteens, then the fives.
