Science Toy II Golf ball roller coaster

admin

Golf ball roller coasterI have made a bunch of these over the past few years here is the latest one. I hope to sell some to other science teachers in a physics workshop I teach. It illustrates Potential and Kinetic energy. My students and children love to play with it. Attached Images
Reply:The two pieces butt up against each other nicely I must have had something under the wood of the one so it is elevated.
Reply:That's looks prety cool...how did you roll the angle?
Reply:ThanksI put a 10" pipe in a vice and clamped the angle iron to the pipe with a pair of vice grips. Then muscled the angle iron around the pipe. You have to move the vice grips a few times but it is really quite simple.reber
Reply:Hey Reebs, once again, awesome work.  I forget what grade it is that you teach, but where I went to school, the students had to build a roller coaster for one of the science classes.  I didn't build one because I didn't take that particular class, but it's usually a 9th grade class.  Some of the designs I saw were pretty neat, just waiting for my nephew to hit HS so I can help him with his, nobody else welds them.Contact me for any metal polishing needs you may have, my avatar is a pic of a standard, painted fire axe that I ground, sanded polished and buffed to a mirror finish.

Reply:That's great.  I'd challenge the students to come up with a formula that predicts the height from which the ball must be dropped to make a gravity defying revolution of the first loop.
Reply:Neat twist Tim I might try that idea.
