Practical Advice for Marble Roller Coaster Construction

1. Practical Advice for MarbleRoller Coaster Construction DiscoverE Project 2019

2. Basic Thrill Ideas Banked curves Loops Jumps Make it FUN!

3. Potential Gotcha’s – Too steep Coaster will get too much speed and jump off the track in subsequent transitions

4. Potential Gotcha’s – Bad joints/connections Marble will be blocked from rolling properly; could slow/stop or jump the track Wad of tape

5. Marble won’t make it up the hill Potential Gotcha’s – Too much height on next hill

6. Potential Gotcha’s – Too sharp of a peak on next hill • Marble will jump off the hill

7. Potential Gotcha’s – Twisted track Marble can’t stay in the groove

8. Too high – can’t complete the loop Not enough support – loop will deform when marble rolls on it Note: Elliptical loop is better than round loop Potential Gotcha’s – Loop

9. Potential Gotcha’s – Kinks & sharp dips • Marble will bounce off track

10. Potential Gotcha’s – Doubled back track • Marble will fall to ground

11. Potential Gotcha’s – Curves without banks Marble will jump track 

12. Potential Gotcha’s – Insufficient support Weight/Force of marble will cause track to sag/move

13. Summary Avoid Too steep Bad connections/joints Too low or too high 2nd hills Twisted track (unless used for proper banking) Sloppy loops Kinks Double backing the track Insufficient track support
