I'm making a roller coaster model for science--the whole physics in action thing. I need to include 2 loops, 2 hills, and 1 turn. We can have the starting point as high as 1 meter, but no more. I'm making it out of duct tape and wire, so it's not closed on top. I'm having trouble getting the marble to go through the two loops without falling or not going through them at all. Can anybody help? Also, any tips for later? Thanks in advance! <3

This is off the top of my head. Your velocity will be close too m*g*h=1/2*mv^2
h is the drop from your start to the top of the loop in meters
g=9.81 m/s^2
Velocity is 2*g*h^.5= v
m*v^2/r>m*g
Substiture,
2*g*h/r>g
h/r>1/2
r< 2*h
I would check this it has been a long time for me.
Make the radious of the loop smaller.
