I started setting up the roller coaster at around noon today, February 15. I first took the pipe insulation to cut it in half. On one side of the insulation, there was a perforation, making the cutting easier for me. I then started to put up the track. I used a lamp, a chair, and a little rocking horse as supports for the track. Putting it up turned out to be more dangerous than expected. I had to stand on a stool so I could reach the top of the lamp, but then, I almost fell flat on my face. Luckily, the stool tipped forward and backward, and then settled. After that, setting up went just as planned. Type this into the URL to see (most of) the finished product! file:///Users/dani/Pictures/iPhoto%20Library/Originals/2009/Roll%2031/DSC04234.JPG
After taking a little over half an hour to set up the track, the testing began. I was going to change the angle of the lift hill from 45, to 60, and then to 75 degrees. The first few tests with the 45 degree angle did not look good. It kept falling off the track at the loop. The same goes for the 75 degree angle tests. They nearly mirrored the 45 degree tests. However, all but one of the sixty degree tests came out perfect. It just gave me an enthusiastic feeling to see that little marble go through that big loop, not once, but twice. Doing all of this only took me about ten minutes. If I could do the all again, I would (without the almost falling off the stool part, of course)!
