I'm building a science project with my little sister, and we quite frankly need some help. The plan is to make a little rollercoaster out of plastic tubing as the track. It's kind of thick, so it doesn't bend very well. We've been straightening it out for a couple days, but it's still slightly wavy. We need to get it into a solid position. The plan is to support it on some boxes, and maybe tape it down so it holds it's form.But, there is a part in the rollercoaster where it needs to be extremely straight. Any ideas??
Heat it where you want the bend. If it is small tubing and depending on what it is made of, place where you want the bend to be in boiling water, take it out, bend it to shape and hold it there until it cools. If it is of a better material or thicker, wrap it with aluminum foil and hold it over a candle, but beware that it will get very hot and may start to melt. P.S. After reading again, you want to straighten it, so you will need to heat it and then roll it back and forth slowly until it cools.
