Fireworks, Archery, Rollercoaster!

I built this world on New Years 2013 just for fun. It turned out to be a fun world to play on for a little bit. There is an automatic fireworks display, an archery range, and a rollercoaster. (actually two, my brother built the one in the desert). There is also a dam built away from the main area.

To use the fireworks, you make sure the "stop" lever is off, then press the button once. The fireworks will start and will continue until they run out or you turn on the stop. Note: the fireworks may go on for a few seconds after the stop is turned on.

It may be almost out of fireworks so to load it up, follow the path under the observation room and put fireworks in the dispensers.

Follow the glowstone to the dam.

This world isn't much but I thought I would share it for fun. Enjoy!
