Build an Indoor Willow Feeder - PEP BB greywillow.straw.indoorwillow

This is a badge bit (BB) that is part of the PEP curriculum.  Completing this BB is part of getting the straw badge in Greywater and Willow Feeders.

For this Badge Bit you will build an indoor willow feeder.  You may get extra points in Electricity if you include a fan.

To complete this BB, the minimum requirements are:
   inside of a house that’s heated in the winter
       not a shed, or other kind of out-building
   includes a urine diverter, which drains to a mulch pit with at least one willow tree
       creating mulch pits are a different BB
   includes some system to ensure willow feeder is odorless
       air from the room moves into the “box” and then outside (fan, stack effect, trombe wall, etc)
   includes a fly trap on the vent
   box containing willow feeder can is relatively air tight
       when the seat lid is down, a very small amount of air will be able to move into the box and out the vent
       the lid and seat might need to be modified to to have a smaller air gap to improve the “seal”
   three cans (one active and two spares), each has
       24 gallon or larger capacity
       a four inch ventilator (with jagged bottom) on side
       at least six inches of sawdust and/or wood chips in the bottom
       show where two empty cans are standing by for future use
   includes a hand crafted, laminated information sheet that details how a willow feeder works on one side and how to deal with shark week on the other side. Lots of drawings.

To show you've completed this Badge Bit, you must show proof of the following (as pictures or a video < 2 mins):
 - show before, progress, and after of building an indoor willow feeder
 - demonstrate that it meets the above requirements
