Now I know what you are thinking, some of these pictures use cardboard instead of plastic. This method is so good that you can use cardboard and plastic for the turns. You start with a long 3 foot track, (you can use any size but it must be the same length as the track you are going to connect to it, and do not forget about the rails.) Next you want to make the track bendy to do that you nead to cut lines in the back of the cardboard or corrugated plastic. (As seen in the last picture.) Next you will cut 3 or 6 slits in the track, DO NOT CUT THROUGH THE RAILS. You want to cut one in the center and the rest of the cuts can be measured. You have now made some flaps. (As seen in the second to last picture.) The next thing to do is to fold the flaps over each other, so that you can bend the track to get a smooth turn. When you have the desired shape you can use tape to hold it together.(As seen in the third picture.) And that is how you do it😎. If you managed to make it please let me know. I hope you guys have any ideas on this method, if you do please tell me.
