Where can I find out how to build a homemade roller coaster?

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.

I can't help you build one from scratch, but SkyMall sells a kit to set one up.  Go to http://www.skymall.com and do a search for ice rink.

http://educate-yourself.org/fe/fejoewatercell.shtml\nI'm unsure of anything that describes how to really make one.\nThis site tries, but it's rather goofy to follow. Maybe you'll have better luck that I would.

I'm not absolutely certain what you are asking, but assuming you want to make toys and furniture I will offer the following suggestions.\n\n1.  Go to The Public Broadcasting System's web site.  A man named Norm Abram (spelling uncertain) has a show called The New Yankee Workshop.  If you can link to his web site he offers plans for every project he does on the show.  He is very entertaining and informative.\n\n2.  Do It Yourself (DIY) is a cable network.  They have a web site that offers a similar service.\n\n3.  Go to your local home improvement store (Lowes, Home Depot, or similar) and go through the magazine racks.  There are dozens of magazines with projects from the simple to the ornate.
