Goliath - Giant Pickle
Just reminded me that when we did our David and Goliath rotation years ago I drew a 9 ft Giant Pickle, painted it, and had it laminated (had to cut it into 6 sections to fit a local store's laminating machine, then taped it back together with clear packing tape).
Why a pickle? In our "David and Goliath" Movie Workshop we watched the VeggieTales "Dave and the Giant Pickle" and so why I decided, for fun, to go with the Giant Pickle.
We used it in our Games workshop were we threw Suction Cup balls at it.
Check out how others used a giant Goliath in their workshops here Amy's Games Workshop and Carol's Game Workshop.
Doing large props like Laura did above and others at this site have done, and placing it in a well seen spot, will attract lots of attention to your program!
