i am a 13 year old in New Zealand and i came across a video of someone who made there own roller coaster so i decided to make my own.
ive had from 6 to 18 year olds try this out and almost all were suscesful (two people around 10-13 fell of the track but none hurt)
for those of you who want to make one here are some tips hings i didif you have something like a BIG HEAVY and fairly tall tree stump for the start is fine but make shure its stablewide or youl make it tip.
when your nailing the fence palings i use eather a pice of scrap wood for conections or a pice of fence cut smaller and put across the join (like tape!) and then nailed it.
for a small bump or hill make small lengths of track, join it and prop it up with bricks or logs.
so basicly if you can cut and nail wood and have lots of it its pritty easy.
try to make a light curve by making pices like this /| as spacers in between the joints but if its too tight eather lean hard or fall of the track.
DO NOT MAKE THIS ANY HIGHER THEN 1METRE UNLES YOU HAVE PROPER RAILINGS!
or it will hurt... real bad.
hope all gose well and please send me pictures or a video when your done.
thank you for waching and reading.
