A Little Background...

• We came across a problem--the world was going to
  be destroyed by the Empires Deathstar.
• We were then given a toolbox of miscellaneous
  items and told that if we failed to create an
  accurate MacGyver shooter, then the world would
  most certainly be annihilated.
• Did we succeed???

Our Goal

• To create a launching mechanism capable of
  projecting a small velcro ball (nuclear missile)
  at a target (evil Deathstar) positioned 7 ft
  away, using only various materials provided in
  our MacGyver Equipment Kit.

Division of Labor

• We started out working together in class, each
  experimenting with materials, playing around with
  individual ideas.
• Becky Riedesel slides 1 and 2, constructed
  basic launch mechanism, final deconstruction,
  final and bonus launches, determined aim/angle
  for bonus launches
• Richie Dettloff slides 3 and 4, put all slides
  together into one show, established legal launch
  release idea, practice and final launches,
  constructed base for launch mechanism
• Brianna Morrison slides 5 and 6, constructed
  original design, carried out launch procedure,
  decided on how to adjust angle, practice, final,
  and bonus launches
• Rick Petersen slides 7 and 8, built base for
  launch mechanism, determined stabilization method
  for the base, practice and final launches

Design Process

• We all experimented in class with various
  materials and ideas
• Constructed an original design with mouse trap
  and release bucket
• Decided it was a bad idea because it had no
  precise aim or force
• Constructed a second prototype with PVC pipe,
  rubber bands, and a launching ram/rod
• Practiced quite a bit in order to get aim and
  launch procedure as accurate as possible
• Launched in class with each member assisting in
  the process of aiming the mechanism to hopefully
  attain optimum performance
• Completed slide show presentation
• If anyone disagreed about ideas, it was kept
  private, and we all got along well
• Each person did what was possible, and our parts
  ended up fitting together successfully

Results

• The things we tested!
• At first we tried to center our handcrafted,
  delightfully tacky and unrefined Macshooter
  around the mouse trap- seeing as how the mouse
  trap could provide us the energy needed to launch
  our ball at least 7ft.
• We then decided, due to some technical
  difficulties, to test the PVC pipe with the
  slender radial piece of wood! It was in our best
  interest to combine these two things, along with
  rubber bands, to perfect our Macshooter!

Statistical Results

• We tested the Macshooter enough times in order to
  align it just right to where the ball would hit
  the target. It may have not been precise, but it
  was accurate.
• Our results showed that during our test trials it
  would hit the target and stick about 75 of the
  time. Now our actual shots didnt quite work out
  so well! During our actual attempts it only
  succeeded about 50 of the time, so we would say
  it works out to a smooth 62.5.

Conclusions

• Our Macshooter proves to be of the upmost
  importance, as it was built by the Engineering
  tycoons of our future! Its pretty amazing how
  one team can take a PVC pipe, some rubber bands,
  a wooden pole, and a small ball and project it at
  least 7ft. Now I wouldnt say our Macshooter was
  completely original because there were a bunch of
  clones in the classroom, but that was bound to
  happen because a lot of people had the same
  general idea with a couple of minor differences.
  I mean, there were only so many ways you could
  build this crazy project using the materials
  given!

Even More Conclusions

• Successful?
• I dont think our Macshooter was the most
  interesting piece of art. I mean Van Gogh would
  have laughed, but it did what we wanted it to do.
  
• It may have not been extremely precise but it was
  more than 60 accurate which is decent. Im
  actually sure that we hit the target almost every
  time, but it doesnt count unless it sticks so we
  had some issues in that respect.
• All in all, we are extremely proud of what we
  constructed given the time and materials used!
  The only thing we could have improved was to
  increase the amount of time we spent on
  perfecting its sticking abilities! Case closed!
