Science Buddies: "Ask an Expert"

im working on a research page for my trebuchet science fair project and i ran out of topics and i need new ones my already written topics are(the science behind the trebuchet) and (the history and what the trebuchet purpose was.)

Hi,
How about a topic that examines the future use of the Trebuchet? I did a quick google search and came across several discussion on launching things into space (not really doable). May be you can improvise on that and look at other applications such as transporting goods with this method?

Good Luck!
