AND

TASK

Each house has to build one trebuchet and one catapult.
A "KIT" is provided to build the basic frame.
Success is all about the details of the launch mechanism.

3 challenges

distance

who can fire a water balloon the furthest

 

accuracy 

get the water balloon closest to the target

 

moving target

can you hit the teachers?

LINKS

yours won't be quite as big as the ones in the links, but very much on the same lines

safety

power tools are dangerous.  careful!  if you are not comfortable using the tools, ask for help.

getting hit in the face by either a catapult or trebuchet will hurt.  take particular care when launching - stand back.
