Inventa really lends itself to the sort of mechanisms and structures
that need to be developed for these field events.
Create a (lever) mechanism that will project a small missile (rolled
up paper) as far as possible within a set area. You will need to create
the shotput range which fans out from the lever and is marked off appropriately.
Anything landing outside this area is not allowed.
Create a spinning mechanism that will release its projectile at the
appropriate point to fling it into the marked area (see above).
Version 1 - Design and make a mechanisms that will "jump" over a bar
that gets progressively higher.
Version 2 - Design and make a mechanism that will throw a (model) person
over a bar that gets progressively higher.
Same idea as above but this time they must get as far lengthways as
