Why do people struggle to open sealed bottles?

• When you preserve food in bottles, because of the
  heat inside the bottle

The air pressure inside the bottle is less than
outside the bottle
This causes a vacuum that prevents us from
opening the bottle

To overcome this, we need a machine.

Can you describe the type of levers and their
functions?
With a little effort you can excerpt a lot of
force on the lid of the bottle.
For more information on levers order a brochure
from us.

But a brilliant idea solved the problem.
Open the bottle like father.
This design was then refined and compared with
similar solutions found in removing oil filters
from cars.

Can you make an artefact from leather solving the
problem?
I planned a production schedule and acquire all
the needed tools.
Using safe work procedures I made the artifact.
With a bit of finishing the artifact was complete.

Can you evaluate the process that you are
following in solving the problem?
Evaluate myself during the process with
checklists. Draw up a final evaluation
checklist. Test it with the old people. Re-define
and alter product. Present final product.
