You will need several rubberbands, some string, 8 rods, and 2 white connectors(the ones with 8 spots to connect to. You also need 2 of the brown connectors that connect the red chain gear wheel to a rod. And a grey wheel.
Tie the rubberbands together, so they stretch to the length of the launch track. When all the rubberbands are tied together, tie the end rubberband cord to 4 chain links.
Take your 8 rods and snap them to the 2 white connectors so they make a cylinder.
Take the cylinder and put a rod through the center. Put the brown wheel connectors on the rod and make it so the rod and the cylinder are joined. Next put the rod so that it is at the far end of the launch track and it can spin freely.
Tie the string to the cylinder and thread it through the hole in green track connectors all the way back to the station end. Put a wheel at the station end of the launch track. Put the string around the wheel and tie it to the other end of the chain link. Make sure there is enough string so that it can get to the far end of the launch track with out stopping.
For the last step, tie the free end of the rubberbands to something sturdy at the far end of the launch track.
If you build it correctly, you can spin the cylinder so that it pulls the chain link back to the station and you can hook the train to the chain link. Then you can let go of the cylinder and the train will launch.
I tied my rubberbands to a weight so I can move the weight and make the launch more powerful.

It is more complicated that the Rippin Rocket, but it only needs one launcher and it looks better.
